MEASURING GUIDE
Nail the perfect fit.
Arguably the most important part of selecting your suit is getting the size right. Too large and you look like you’re wearing hand me downs. Too small and you look like you’ve just had a growth spurt in secondary school.
To ensure your rented suit fits like a glove, we offer three convenient options:

Having measurements taken with a measuring tape is preferable. However, if you don't have a measuring tape or personal tailor at home, we recommend the Sizer app with two main notes:
- The app really does work but wear underwear when taking the body scan. Clothes will increase your sizes.
- The app measures in-seam to the floor whereas we measure to where the the trouser will sit. We recommend you minus 1-2 inches off the app's inseam measurement.
A Suit You Own
Start with a well-fitting suit or separates you already own.
Already own a suit or separates that fit well? Look at the labels! Rathbones Tailor uses UK sizing, which is typically displayed as:
- Jackets: A number followed by a letter (e.g., 40R). The number indicates chest size in inches, while the letter represents jacket length (R = Regular, L = Long, etc.).
- Trousers: Two numbers separated by a slash (e.g., 34/32). The first number is the waist size in inches, and the second is the inseam length (in inches). Important: Jeans and suit trousers use different sizing systems, so don't rely on your denim size for suit trousers.
