Size M Brazilian = US XS/S This is an amazing piece from the early 2000s by the iconic Brazilian designer Rosa Chá. Nothing like it! Pink, green and orange floral design with a back strap and very skimpy bum. I am 5”10 and this does not stretch enough for my torso to fit comfortably - this would best suit someone 5”8 and under in my opinion, or maybe if your torso is shorter. The top fits an A cup or small B. SO sexy! Paid nearly $300 USD for this in 2009. This is still in impeccable shape, only worn a couple times.
