Yes, I find their clothing runs true to size. Many of their pieces are fitted so you might want to consider sizing up for a looser fit. For example, I find the cotton modal tee shirt from Quince runs 1-2 sizes small in comparison to drapey, looser fitting tees from other brands. If you want a fitted tee, order your regular size. If you want a slightly oversized fit, which has become the norm for a lot of tee shirts, go 1-2 sizes up.
