I LOVE these shirts! I am 138lbs, 34D, 5’8, and typically wear a small/medium in Womens’s. I ordered a Medium which for great. Today I paired them with Capri pants, heels, jewelers, and a blazer for work. But, i love them with just a pair of jeans and flats for the weekends. The other thing I LOVE is the sleeves! They’re not short like most t-shirts. They’re long enough to cover my bus drivers (arm fat) but not too long to make them hot! These shirts are soft, classy, and flow perfectly.
