I just got this today. I’ve wanted it for a long time & im usually a size small or medium, but those sizes were out. So I had to get the only size left which was the xsmall. I was worried it would be very tight, but when I put it on it fit perfectly. I’m 5’8 & 130 lbs. Its absolutely beautiful & so soft & stretchy. I definitely recommend & my opinion would be to size down.
