SIZE & FIT GUIDE

FIT:

Athletic tailored fit — engineered to enhance the shoulders, chest, and arms while maintaining a streamlined silhouette through the body. The premium stretch fabric moves naturally with you, delivering a sharp, sculpted look without restricting comfort or performance.

 

LENGTH:

Modern performance length — cut to sit cleanly at the waist for a refined appearance whether worn on its own or layered. Designed to pair effortlessly with tailored trousers, joggers, shorts, or elevated casual essentials.

Most customers find The Mayfair Quarter Zip fits true to size with a close, athletic fit. We recommend selecting your usual size for the intended ONIS London silhouette.

 

PRO TIP:

The Mayfair Quarter Zip is crafted from a premium stretch performance blend designed to contour naturally to the body while retaining its shape wear after wear. Prefer a sharp, athletic fit? Stay true to size. For a slightly more relaxed fit or additional layering room, we recommend sizing up.
