Rounding up my favorite white tshirts! I’ve tried a lotttt of the big brands and these are the ones I love the most and balance thickness with breathability. I’m 5’7” and I sized up two sizes to a medium in the first baby tee shirt, size small in the two from Aritzia, and XS in the heavyweight tee from Abercrombie LTKFindsUnder100 LTKStyleTip LTKSaleAlert
