Size Guide (Men & Women)
Size Guide – Men's & Women's Apparel

About sizing & fit

Apparel sizing is not universal. Measurements can vary slightly by manufacturer, style, fabric, and fit (slim vs. relaxed), even when the size label is the same.

Best way to choose your size:
1) Start with this size guide
2) Check the product description for fit notes (runs small / relaxed fit / slim cut)
3) If you’re between sizes, we generally recommend sizing up—especially for non-stretch fabrics or outerwear

Use this guide to choose your size for most tops, jackets, pants, jeans, shorts, skirts, and casual dresses. If you are between sizes, we recommend sizing up for a more relaxed fit.
