The ideal white button-up shirt is first chosen by the right size and style for the occasion. In our selection, you’ll find sizes from 36 to 46 and Regular fits for a timeless drape. Materials vary from microfiber-polyester to cotton-polyester, including 100% cotton—each offering its own level of softness, absorbency, and resistance to wrinkling. Collars and sleeves also differ: classic collars, simple cuffs, and long or short sleeves to suit either formal or casual looks. Since the shirt is white, choose a fabric that supports the overall look of the outfit you’re wearing.
