Why Clothes Never Seem to Fit or Look Good in Stores

It’s Not the Mirror, and It’s Not You

You go into a fitting room feeling reasonably good about yourself and the outfit you’re wearing to the shops. You come out twenty minutes later having decided that you have terrible legs, that your stomach has staged some kind of coup, and that you should probably not leave the house until spring.  And how you looked in the clothes you tried on?  Even worse.

Then you get home, look in your own mirror, and think: hang on. I look fine.

Most of us treat the fitting room as the moment of truth. It’s harsh, it’s honest, it’s the real story. That’s exactly backwards. The fitting room is the least reliable information you will receive all day, and once you understand why, you get to stop taking its word for anything.

The number on the label is not a measurement

Let’s start with the thing that upsets people most, because it’s also the easiest to disprove.

Tammy Kinley, a researcher at the University of North Texas, measured 1,011 pairs of women’s trousers for a study published in the Clothing and Textiles Research Journal. She found inconsistency in every single size category. Size 4 varied the most, followed by size 6. More expensive brands were generally cut larger across the board.

Read that again. Not “some brands run small.” Every category. A thousand pairs of trousers, and no agreement about what any of the numbers meant.

So when you try on three size 12 dresses and one zips, one gapes and one refuses to go past your ribs, you have not discovered a fact about your body. You have discovered that three different companies made three different guesses, in three different countries, for three different imaginary women.

I have never had what you’d call a manufacturing standard body, which is one of the reasons I ended up doing this work at all. I once tried on somewhere between forty and fifty pairs of white jeans before I found a pair I’d actually wear. Forty pairs. If sizing were a system, that would be impossible. It isn’t a system. It’s a suggestion, written in a language nobody translated.  Just like you, nobody came and took my measurements and constructed those jeans to fit my exact body. So it’s always going to be a hit-and-miss affair with way more misses than hits, when shopping for clothes, and I no longer take it personally.

The room is lit to make you look worse

Here’s the part that made me laugh when I found it, because it turns out the retail industry knows exactly what it’s doing to you.

There’s academic research on this: a University of Florida study by Baumstarck and Park looking at how the direction of dressing room lighting affects how consumers perceive themselves. 60 women aged 18 to 35, randomly assigned to either an overhead-lit or a frontally-lit dressing room in a real boutique, were told to shop and try things on. Frontal lighting won significantly on both self-evaluation and room evaluation, with the strongest effects on facial shadowing and perceived roominess. But the really telling evidence is in the patent applications for retail lighting systems. Lighting companies have to explain, in writing, why their product is needed. So they spell it out: customers in retail dressing rooms are all too often unhappy with what they see in the mirror, perceiving that the conditions highlight or even create under-eye shadows, uneven skin tone and texture, wrinkles, unflattering fat distribution and cellulite. But the overhead lighting is considered to be better for the garments, even though it makes you look bad. The patents state outright that this is often a painful experience and that it affects purchasing decisions.

That’s not a body positivity influencer’s opinion. That’s an engineering document.

Overhead lighting is the main culprit. Light coming straight down from above carves shadows underneath everything: under your eyes, under your chin, under your bust, across any dimple or texture in your skin. It’s the same principle as a torch under the face at a campfire, just inverted, and it’s just as much of a special effect. Frontal, diffused light does the opposite, which is precisely why every good makeup mirror in the world has bulbs around the sides rather than a single spotlight above.

So the woman in the mirror under those downlights is not a more honest version of you. She’s a poorly lit version of you. There’s a difference, and it’s the same difference between a passport photo and a portrait.

So why on earth doesn’t anyone fix it?

This is the question everybody asks next, and the answer is duller and somehow more annoying than a conspiracy.

A fitting room is what the trade calls non-selling space. It holds no stock, and it rings up no sales, so it gets the smallest footprint and the cheapest fit-out that will pass inspection. It’s also, according to retail patent filings, the place where most clothing theft happens, which is why cubicles are so often locked or watched. So the design brief for that little room is privacy, security and cost. Nobody in that meeting is thinking about how the light lands on your upper arms.

Then there’s the ceiling. One recessed downlight is one hole, one cable and one fitting. Lighting down either side of the mirror means different wiring, different joinery and a different budget, multiplied by every store in the chain. The cheap template wins by default, and templates outlive the people who wrote them.

And almost nobody checks the result. One retail analytics firm reports that 91% of clothing retailers don’t know their own store’s conversion rate at all. Another notes that retailers measure the front door obsessively and the fitting rooms barely at all. If nobody measures it, bad lighting never appears in the accounts. It simply shows up as “she didn’t buy the dress”, which gets filed as a product problem, and the lighting is never even a suspect.

But here’s the real reason nothing changes. Even lit like a police interview, the fitting room works. Industry figures put fitting room conversion at around 67 per cent, against roughly 10 per cent for shoppers who never go in. (Those numbers circulate between retail suppliers rather than academic journals, so hold them loosely, but the direction of travel isn’t disputed by anyone.) That grim little cubicle still converts two thirds of everyone who walks into it. A failure that profitable never gets escalated to anybody who could fix it.

And when it does fail, they usually still get paid. People rarely go home empty-handed, which we’ll talk about why in a moment.

The other kind of manipulation

Now, some retailers do go the other way deliberately. Ann Taylor’s fitting rooms have been described as using six separate light sources and three different bulb types, mixed specifically so the light flatters the customer as well as the garment. There is a whole lighting industry selling exactly this, with recommended colour temperatures and specific attention to how well a bulb renders the reds in skin tones.

And I want you to be just as suspicious of that.

A fitting room that makes you look better than your own bedroom is not being kind to you. It’s the same lever, pulled in the opposite direction. That’s the dress you fell madly in love with in the shop, brought home, tried on once in your own hallway and quietly never wore again.

Which is the thing worth sitting with. The horrible cubicle and the unworn dress in your wardrobe are not two separate problems. They’re the same story, told from opposite ends.

Mirrors turn up the volume on whatever you already believe

This next bit is the piece that connects the lighting to the feeling, and it’s my favourite finding of the lot.

Psychologists talk about self-discrepancy, which is the gap between the person you are and the person you’d ideally be. We all carry one. It’s normal. Most of the time it sits quietly in the background.

Phillips and Silvia found that people felt significantly more distressed when confronted with their self-discrepancies while sitting in front of a mirror. People not in front of a mirror, and therefore less self-aware in that moment, were not significantly affected by the same discrepancies.

So the mirror doesn’t create the feeling. It amplifies it. Whatever quiet story you were already telling yourself about your body gets turned up to full volume the second you’re looking at your reflection.

Now put the three things together, which is the bit nobody does. You are standing half undressed, under lighting engineered to exaggerate texture and shadow, holding a garment with an arbitrary number on it that has just told you something you didn’t want to hear, in front of a mirror that magnifies every existing insecurity you brought in with you.

That’s not a fitting room. That’s an ambush.

What happens when the size is bigger than you expected

Researchers publishing in the Journal of Consumer Psychology looked at what actually happens when a woman needs a larger size than she anticipated. Across five studies, they found that larger sizes led to negative evaluations of the clothing itself, and that the effect was driven by appearance self-esteem. The garment got the blame for the feeling.

Kinley ran a follow-up in 2010 in the Family and Consumer Sciences Research Journal, which found that smaller sizes improved body image, particularly for younger university-aged women, but that needing a larger size did not significantly affect self-esteem or body image.  She also found the effect was much stronger for university-aged women than for women in their forties and fifties who were not as affected by the need to go up a size; it sounds to me like, as we age, we become less susceptible to those sneaky retailers and their tricks!

Then it gets interesting. You’d assume a knock to your self-esteem would make you buy less. It does the opposite. The researchers found that larger sizes can actually increase spending, because people engage in what’s called compensatory consumption. They buy something else to repair the feeling.

And note what they buy. Participants reached for other products that would affirm how they looked, things without a size on them, rather than just anything that would cheer them up. Which explains a great deal about why so many of us have walked out of a shop empty-handed on the dress front and yet somehow holding a scarf, a lipstick and a pair of earrings.

The scarf isn’t a scarf. It’s a plaster.

The finding that changes everything

Now here’s the one I want you to actually take home.

In the same body of research, the experimenters bolstered some participants’ appearance self-esteem before the shopping scenario began. For those women, the size label had no effect on their mood at all.

Same clothes. Same numbers. Different starting point. The whole mechanism collapsed.

That tells us something enormously useful, and it isn’t “just love yourself more,” which is the sort of advice that has never once helped anybody in a fitting room. It’s more precise than that. The damage a size label can do to you is not fixed. It depends on what you already think about how you look when you walk in the door.

Which means the real work is not in the fitting room. It’s before it.

So what do you actually do

A few things that follow directly from the research:

1. Before you look at yourself in the change room mirror: Remember that the lighting will be terrible and that it’s unflattering to everyone, not just you.  Don’t take it personally.
2. Do your hair and makeup.  Before you shop, make sure you’re happy with your hair and makeup.  If you’re not, that feeling is only going to be inflated in those change rooms.
3. Cut the tags out. If a number on a label can move your mood, remove the number. You are not obliged to keep information that only functions as a perceived insult.
4. Take one photo in natural light. Not to post anywhere, just for you. Stand near a window that isn’t bringing in direct sunlight, front-on to the light, and photograph the outfit. Since you now know that one room is lit to flatten you and another might be lit to flatter you, a window is the only impartial judge in the building. It removes the overhead shadows and the reflection that amplifies your inner monologue.
5. Shop on a good day, early. Never at the end of a long day, and never when you’re already feeling low about how you look. That’s not vanity. That’s the research: your starting self-esteem determines how much the experience can hurt you.
6. Judge the garment, not yourself. Say it out loud in the cubicle if you need to. “This wasn’t designed to fit me” rather than, “there’s something wrong with me” as they are completely different sentences, and only one of them is a fact (it’s the first one if you hadn’t already guessed).
7. Bring three sizes into the fitting room. Every time. If you only take in one, the label becomes a verdict. If you take in three, it becomes what it always was: a guess by a stranger who has never met your body.  Remember, sizing is arbitrary and inconsistent, even within brands.

Because that’s the thing worth holding onto. Your measurements are real. Your shape is real. The way fabric falls on you is real, and it’s knowable, and it’s the actual skill of dressing well.  And it’s what I teach inside my 7 Steps to Style program if you’re searching for the answers.

The number on the tag is none of those things. It’s a decision made in a boardroom by someone who was never thinking about you.

Next time you’re in a fitting room, and something doesn’t fit, try saying “this garment was poorly designed” instead of “my body is wrong for this garment,” and notice what changes. That one swap is where all of this starts.
