Quick answer: When one trouser leg looks longer than the other, the cause is usually the client rather than the cloth: a lower hip, a shorter leg or a habit of standing on one side. Measure both legs on the MTM order, write a finished length for each side, and check the break of each leg separately on the sample. Shi Yuan (Suit Factory) takes MTM from 1 and bulk from 50 per style for overseas tailor shops, MTM boutiques and private-label brands, not retail — send both leg measurements and a front photo on WhatsApp.
A client stands at the mirror in his new suit. The left trouser leg breaks cleanly on the shoe. The right one folds twice. The tailor checks the hems: they are identical. The trousers are symmetrical; the client is not. Many people are slightly uneven left to right, and a suit shows it at the hem. Shoulder differences are the jacket side of the same story, set out in the low shoulder order note.
Why does one trouser leg look longer than the other?
There are three common reasons. A lower hip on one side drops that side of the waistband, so the leg below it hangs further down. A true leg-length difference does the same from the leg itself. A standing habit, such as resting weight on one leg, makes the unweighted side look longer in the mirror. The fitter's job is to tell which one it is, because the order note differs.
If the waistband sits level and the legs still differ, the leg is the cause. If the waistband dips on one side, the hip is the cause. If the difference disappears when the client stands evenly, it is stance, and the fitter should note it rather than change the pattern.
Diagnosing the difference
| What the fitter sees | Likely cause | What to write | Sample check |
|---|---|---|---|
| Waistband dips on one side | Lower hip on that side | Low hip note, left or right | Waistband level from the front |
| Waistband level, one leg breaks more | Leg-length difference | Separate finished length per leg | Each break matches its note |
| Difference vanishes when standing evenly | Stance habit | Photo note, no pattern change | Compare relaxed and even stance |
| Difference plus shoulder drop on same side | Overall posture tilt | Low hip and low shoulder notes | Jacket hem and trouser hem both level |
| Client wears a shoe lift | Footwear correction | Measure with the usual shoes on | Fit check in the same shoes |
Same table as a list
- Waistband dips on one side: a lower hip on that side — write a low hip note, left or right; check the waistband is level from the front.
- Waistband level, one leg breaks more: a leg-length difference — write a separate finished length per leg; check each break matches its note.
- Difference vanishes when standing evenly: a stance habit — write a photo note, no pattern change; compare relaxed and even stance.
- Difference plus a shoulder drop on the same side: an overall posture tilt — write low hip and low shoulder notes; check both hems are level.
- Client wears a shoe lift: a footwear correction — measure with his usual shoes on; check the fit in the same shoes.
How to measure both legs
Measure the outside leg on both sides, from the waistband position to the floor, with the client standing in the shoes he will wear with the suit. Then measure the inside leg on both sides. Mark the finished length you want on each side, using the break the client prefers. The break choice itself is covered in the trouser break guide; here the point is to apply that choice to each leg.
Write the two lengths as left and right from the wearer's view, and say so on the order. Left and right confusion is a common reason a corrected sample comes back with the fix on the wrong side.
Spec lines
- Side convention: "left and right as worn".
- Outside leg: left and right, measured in the client's shoes.
- Finished length: left and right, with the chosen break.
- Hip: "low hip left" or "low hip right" if the waistband dips.
- Leg line: knock knees, bow legs or straight, as its own line.
Leg shape is a different correction from leg length. A client with bowed legs can also have one shorter leg; write both, using the leg line note for the shape.
A worked note
"Client ref A-12. Left and right as worn. Waistband sits level. Right leg shorter. Finished length written for left and right separately, slight break both sides. Measured in his usual shoes. No shoe lift. Front photo standing evenly attached."
At the sample
- Ask the client to stand evenly in the shoes he measured in.
- Photograph from the front and from each side.
- Check the waistband is level.
- Check each leg breaks the way the order says.
- If one side is still off, write which side and by how much it looks off, in words.
Turn-ups and uneven legs
A turn-up makes a length difference more visible because the cuff line is a horizontal mark. If the client wants turn-ups, the two finished lengths matter more. Some shops prefer a plain hem for clients with a strong difference. Write the choice; do not leave it to the factory.
What to send on the first WhatsApp
- Both outside leg and both inside leg measurements, marked left and right as worn.
- Whether the waistband dips on one side.
- A front photo standing evenly, in his usual shoes.
- The break he wants and whether he wants turn-ups.
Which track handles uneven legs?
- MTM — from 1 piece: the client's trousers with left and right lengths written on his order and kept on his fit record.
- Bulk — from 50 per style: a house size run cut symmetrical; a client with a strong difference moves to MTM or is hemmed in the shop.
The sample takes 7–14 days; production takes 14–21 days after measurements, cloth and construction are locked. Production days are not delivery days. How MTM orders from shops are handled is on our made to measure suit factory page, and how a sample is checked is on our sample policy page.

FAQ
What are Shi Yuan's order tracks and clocks? Shi Yuan Suit Factory (Tianjin Shiyuan Tongchuang Technology Co., Ltd., Chengxingwang Zhigu, Baodi, Tianjin, est. 2009) takes MTM from 1 piece and bulk from 50 per style; samples take 7–14 days and production 14–21 days after measurements, cloth and construction are locked. WhatsApp +65 8013 8838.
Should the factory shorten the leg or change the waistband? It depends on the cause. A leg-length difference is handled at the hem length; a lower hip is handled at the waist. The fitter's note decides which.
Can the shop correct it after delivery instead? For a small difference, a shop hem is often enough. For a lower hip, writing it on the order gives a cleaner result than a hem alone.
