Everyone owns a kameez that fits at the shoulder and balloons at the waist, or a blouse that closes but cannot be breathed in. That is not bad luck. It is what happens when garments built around exact fit are sold in sizes built for averages.
A ready-made M fixes ten measurements at once: bust, waist, hips, shoulder, sleeve, length and more, all scaled from one fit model. Real bodies do not scale like that. One person is an M at the bust and an L at the hip; another is an S at the shoulder with long arms. Western casual wear hides this with stretch and loose cuts. A fitted blouse or a structured kameez cannot hide anything.
A saree blouse is cut to sit exactly at the bust and underbust; two centimetres off and it gapes or digs. A churidar sleeve is meant to stack close on the forearm. A lehenga waist carries the full weight of the skirt, so it either sits right or slides. These garments were designed in a world where everything was stitched to measure, and they still assume it.
The fix is not a better size chart; it is your actual naap. On Silai your phone camera measures you in about two minutes, each number landing within about two percent of a tape measure on average. Tailors stitch from those exact numbers, and the Pre-Loved rack compares them against what each second-hand piece was originally cut for, so even ready-made becomes made-for-a-body-like-yours.
