Choosing the right size

It can be easy to get the size wrong when choosing a suit. Suits that are too large can look sloppy, and suits that are too small can look tight and constricting, so choosing the right size really makes a difference.
We'll introduce two ways to make sure you get the size just right.
1. Choose based on your usual size
First, one reliable way of choosing a suit is to base your decision on the size of suits that you usually wear.
Check the size indicated on the label of a suit you wear now, and compare it to the size specifications (shoulder width, dress length, sleeve length, waist, etc.) listed on the AOKI product page.
2. Choose using the size chart
If you want to choose the size in a more detailed way, refer to the size chart below.
For example, someone 172 cm tall with a waist of 81 cm would choose size A6.

Then open the sizing guide tab for the suit you want, and compare your own measurements to those listed for size A6.
