Size Guide

Sizing Philosophy

Project Aston garments are cut true to standard sizing. We follow a European fit — not the extremely slim silhouette of some contemporary brands, and not the generous roominess of traditional tailoring. The proportions are designed for the modern adult male body.

If you are between sizes, size up for outerwear layers; size true for tops worn on their own. When in doubt, reach out — we are easy to contact and will give you a direct answer.

How to Measure

Chest: Measure around the fullest part of your chest, keeping the tape level.

Waist: Measure around the natural waist, approximately one inch above the hip bone.

Inseam: Measure from the crotch seam to the floor along the inside of the leg.

Shoulders: Measure from the edge of one shoulder to the other, straight across the back.
