Sizing | UNTUCKit

Our men's shirts run smaller than traditional large well known brands. If you are right on the border or between sizes, please order one size up. However, women's shirts and shorts run true to size.

Please note these are standard sleeve lengths. Dress shirts sleeve lengths do not translate to casual shirt sleeve lengths. As an example if you wear a 32/33 dress shirt sleeve length then a medium will fit you.

If any questions or confusion please email us at

Sizing Chart


Regular Fit: - Use the sizing chart as a guide, but please note our sizes run on the smaller side. If you are right on the border or between sizes, please order one size up.

Slim Fit - The slim fit is one inch narrower in the chest and two inches narrower in the waist. The sleeves are also slightly more narrow. It's made for, well, slim people.

XXXLC - Stands for XXX Large Classic. As our styles traditionally run on the smaller size, this size fits more like a traditional triple XL.

Tall Sizes - Available in Regular (M,L, XL, XXL, XXXL) and Slim (M, L, XL, XXL) in select styles. Add 2 inches to the Sleeve and Body Length to get the Tall size.
