Does it fit me?

Why does the same size fit differently in every brand?

Letter sizes (S, M, L) and number sizes aren’t standardised across brands. Each brand designs around its own fit model and “body block” — the base pattern it grades up and down from. Two brands can start from different reference bodies, so the same “medium” ends up with different chest, waist and length measurements.

Many brands also use vanity sizing: over time the same label gets attached to larger measurements, so shoppers fit a “smaller” size. The practical result is that the letter on the label tells you very little on its own. The brand’s measurement chart is what means something.

How to read a size chart

A useful size chart lists body or garment measurements in centimetres or inches. Measure yourself once, keep the numbers, and match them to the chart for that specific piece:

• Body or garment measurements? Check which one the chart gives. A garment measurement includes the ease the designer added; a body measurement doesn’t.
• Use the chart for the exact line. Charts can differ between a brand’s collections, and between tops and bottoms.
• Comparing brands? The clothing size converter turns your bust, chest or waist into a starting size in each brand, from the brands’ own published charts.

Between sizes? How to decide

• Stiff or structured fabrics (denim, wool coats, tailored pieces): size up for comfort and movement.
• Very stretchy knits: the smaller size often looks cleaner; size down only if you like a snug fit.
• Layering pieces (jackets, sweaters worn over other clothes): size up so they sit over what’s underneath.
• Length-sensitive pieces (dresses, trousers): check the length measurement against your height and inseam, not just the width.
• Two measurements disagree? Go by the one that matters for the garment: bust or chest for tops, waist and hips for bottoms.

How fabric, stretch and cut change the fit

Even with the right numbers, two pieces in the same size can look completely different on you. Before you buy, check the product page for:

• Fabric composition. Elastane or a knit construction gives; rigid cotton, linen and wovens don’t. Stretch forgives a small mismatch in measurements; a rigid fabric won’t.
• Fabric weight. Heavy fabrics hold their shape; light ones drape and cling.
• Cut and silhouette. Boxy, slim, relaxed, oversized, cropped, longline — the fit description tells you how much room the designer meant there to be.
• The model’s details. Many shops list the model’s height and the size they wear. Compare with your own height to guess where hems will land.

Your proportions — torso length, shoulder width — also decide where seams and hems sit. Numbers can tell you a piece will close; they can’t tell you whether it will look the way you want.

Use reviews and the returns policy

• Read fit reviews, not star ratings. Look for “runs small”, “runs large” or “true to size”, ideally from reviewers who mention their height and usual size.
• Look at customer photos where a shop has them; they show the piece on bodies other than the model’s.
• Check the returns policy before you order: the return window, whether returns are free, and whether sale items can be returned. If you’re unsure between two sizes and returns are easy, some shoppers order both and send one back.

Where a visual preview helps — and where it doesn’t

The question a size chart can’t answer is how does this look on me? That’s what wearfits.me is for. Add a selfie with your height and weight (a full-body photo is optional and raises accuracy), and paste a product link from almost any shop. You get a studio shot of you wearing the piece, like the model on the product page — no prompts. You can mix pieces from several shops into one look to see the whole outfit together.

It is a visual preview, not a size or fit guarantee. Pick the size from the brand’s chart; use the shot to decide whether you like the piece on you. Step-by-step: how to try on clothes online.

A quick checklist before you buy

1. Measure yourself and keep the numbers.
2. Open the size chart for the exact piece and match the measurement that matters.
3. Read the fabric, stretch and fit description.
4. Scan reviews for “runs small / large”.
5. See the piece on you to decide if you like it.
6. Check the returns policy, then order.

Shoppers increasingly expect to see clothes on themselves before they buy, and more shops now offer some form of try-on.
