NUMI: Undershirts for Women.

NUMI’s top-of-the-line undershirts—short sleeve, long sleeve, scoop neck, mock neck, and more—provide the luxury, comfort, and ultra-softness that can’t be duplicated in women’s cotton shirts. The key is in the fabric: NUMI undershirts for women are made of 95% Tencel and 5% Lycra to create a comfortable, compression slimming shirt that you can wear under any top. NUMI offers sweatproof undershirts, the perfect option to replace your basic layering tank tops and cotton camisoles because they keep you dry by trapping underarm sweat and the laser-cut sleeves lay flat and are practically invisible under any blouse. Get the right fit. NUMI’s snug undershirts fit as expected. View our Size Guide to find the perfect size!
