Fit first: why your size label is the wrong place to start
About one in four online clothes orders goes back, and size is the top reason. Labels drift between brands; your measurements don’t. A method that works for every shape.

The four posts before this one were about shape. This one is about something that matters more: fit. A dress in the “right” silhouette still fails if it pulls at the hips, and a jacket in the “wrong” one can look great if the shoulders fit. Here is why size labels let you down, and a method that works for every shape.
The returns problem
In a 2023 survey of 100 US apparel brands and retailers, the average return rate for clothes bought online was 24.4%, about one order in four. More than half named size and fit as the main reason.1 Tested
A survey of sellers, not shoppers. Other reasons made up the rest.
The label is not a measurement
Tammy Kinley measured 1,011 pairs of women’s trousers. Every size was inconsistent, size 4 most of all, and dearer brands tended to run larger.2 When CBC Marketplace measured jeans labelled with a waist size, most were bigger than the label by an inch or more.4 Tested
Brands have a reason to drift. In a later study by Kinley, women who fitted into a smaller size than they expected felt better about themselves.3 That is good for sales and bad for anyone trying to compare one shop with another.
One size, one shape
Size charts give each size one set of measurements, so they assume one shape. The North Carolina State researchers put it plainly: much of the industry sized for the hourglass, while only 8% of the women they scanned had that shape.5 So most people are different sizes in different places. A spoon shape might be a small at the bust, a medium at the waist and a large at the hips. Which one should she buy? It depends on the garment.
Pencil skirt
Choose L
The hips decide. Take in the waist.
A-line dress
Choose M
The skirt flares, so the hips have room.
One spoon-shaped body, small at the bust, medium at the waist and large at the hips, and two garments. The pencil skirt is sized by the hips; the A-line dress by the bust and waist.
A method that works for any shape
- Measure once, with a tape. Bust or chest, waist, hips, shoulders, and height. Part 1 shows where.
- Read the item’s own size chart, not the label. Check whether it gives body measurements or garment measurements. Garment measurements include the room the designer added.
- Find your size in each area. It is normal for them to differ.
- Choose by the area you can’t alter, using the table below. Then have the rest taken in, or accept a little room.
- Allow for stretch. Fabric with elastane forgives a centimetre or two where it is snug.
- Check the length against your height: where will the hem or the sleeve end on you?
| Garment | Choose the size by | Easy to fix afterwards |
|---|---|---|
| Jacket, coat, structured shirt | Shoulders, then chest | Waist, sleeve length |
| T-shirt, knitwear | Chest | Length, a little |
| Sheath or bodycon dress | The larger of bust and hips | Waist |
| A-line or fit-and-flare dress | Bust and waist | Hem |
| Wrap dress | Waist and hips; the wrap adjusts the bust | Hem |
| Pencil skirt | Hips | Waist |
| A-line skirt | Waist | Hem |
| Trousers and jeans | Seat and thighs | Waist, hem |
This is tailoring practice, not a lab result. Stylist convention It works because alterations are cheap where a garment has a seam to take in, and impossible where the cut decides, such as the shoulders of a jacket.
How much room?
Each style is designed with its own room, or ease: none in a bodycon dress, a lot in a trapeze. The one tested number we found is for T-shirts: about 2 to 3 cm of room at the chest made men look smallest, and both tighter and looser looked bigger on larger men.6 Tested For everything else, trust the garment measurements in the chart and compare them with yours.
Dress for how you want to feel
Shape advice is often written as a list of things to hide. The research suggests a better reason to care about fit. Women who were less happy with their bodies used clothes more to hide and enjoyed shopping less.7 Women who saw well-designed dresses on avatars of their own bodies said they felt better about their shape.8 And shape labels themselves shift when the tape moves a little.9 So use your shape as a hint, and your measurements as the facts.
