#SebsLaw: #5 – Undershirts By sebmatthews | April 18, 2017 0 Comment Undershirts hide a multitude of sins. Wear one! p.s. Day-to-day I wear Under Armour. Fits well and washes/dries quickly. When I travel I wear Merino wool shirts. Fits really well, never creases and washes/dries in less than an hour. Bingo.
