FIT QUESTIONS

What size should I choose if I am between two sizes?

For a sharper and closer fit, choose the smaller size. For everyday comfort and more room, choose the larger size.

Does K.O Signature fit tight?

K.O Signature is designed to sit close to the body with support, stretch and comfort. It should feel secure without squeezing.

Are the measurements exact?

The size chart is a fit reference. Small variations of 1–2 cm may happen due to fabric stretch, production tolerance and how the piece is measured.
