Size Guide & Measurement Form
Everything our tailors need to cut your coat, blazer, waistcoat, shirt and trouser — and a form that sends the finished measurement sheet straight to our WhatsApp.
How to Make Your Custom Size
A bespoke garment begins with an accurate body measurement, not a garment size. We never add or subtract ease from what you send us — our cutter applies the allowances for your chosen fit. So measure the body, snug and level, and let us do the rest.
01
Dress correctly
Wear a well-fitting shirt, your usual trousers and normal dress shoes. Empty your pockets.
02
Stand naturally
Stand upright and relaxed in front of a mirror. Never hold your breath or pull your stomach in.
03
Keep the tape level
The tape should be snug but able to rotate. Keep it parallel to the floor all the way round the body.
04
Ask for help
Shoulder, back width and sleeve length need a second person — measurements taken alone are usually short.
05
Use one unit
Record everything in inches or everything in centimetres. Mixing the two is the most common error we see.
06
Send and confirm
Submit the form below. Our cutter reviews the sheet and, if anything looks inconsistent, we schedule a short video call.
