Their pieces tend to run a little more on the larger side, so I tried two different sizes for the bottoms. In Sienna, I tried XS - and in Onyx, I tried XXS. Both did fit, as they stretch up to twice their size, but XS fit me best. For the tops, I'm a 32D bra size and went with XS for both, which was recommended, but I could've done a Small. To give you a better idea: I previously ordered a Medium in a pair of the Skims Cozy Knit Pants, but they honestly fit like an XL.. so in those, I would definitely need an XS. All in all, sizing can be tricky, but their pieces are worth the hype!
