Men's Tops

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 questions@untuckit.com.

Tall Fit- 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.
