The camera scan, in six steps
The scan runs on your phone's camera only; a laptop shows a QR code to continue on your phone. Processing takes about a minute. Wear fitted clothing, keep the room lit, and keep your whole body, head to feet, inside the frame.
How accurate is it?
On average, each measurement lands within about 2% of the true value: a hip that really measures 100 cm usually comes back between 98 and 102 cm. Two things tighten it further: following the on-screen steps carefully, and entering your bra band size, which Silai uses to calibrate all girth measurements. Your tailor always receives the full naap, so for a critical piece they can ask you to confirm a key number with a tape.
The measurements, and how to take them with a tape
These are the ten measurements Silai compares when scoring fit, plus the band. Use a soft measuring tape, snug but never tight, over fitted clothing or none.
- Height: head to feet, standing straight against a wall, no shoes.
- Bust: around the fullest part of the chest, tape level all the way around.
- Bra band (underbust): around the ribcage directly under the bust. This is the number on your bra label, 70 to 120 cm.
- Waist: around the natural waistline, the narrowest point above the navel.
- Hips: around the fullest part of the hips and seat.
- Shoulder width: across the back, shoulder seam to shoulder seam.
- Arm length: shoulder seam to wrist, arm relaxed and slightly bent.
- Armhole: around the shoulder joint, under the armpit and back over the top.
- Bicep: around the fullest part of the upper arm.
- Thigh: around the fullest part of the upper leg.
- Hip to ankle: a length, from the hip bone straight down to the ankle bone. Sets where hemlines fall.
Why fit scores use these
When you browse Pre-Loved, Silai compares every measurement you and the garment share from the list above. A piece that would sit more than about 10% tight anywhere is marked not your fit; roomier differences are shown as loose, which a tailor can usually take in. The chart on each listing shows exactly which measurement sits where, so you and the seller can talk specifics instead of guessing.
