I'm 5'4" with a smaller bust and typically wear an XS/S, but sized down to an XXS and it was the right call. The fit is snug but not restrictive, and genuinely more flattering for it. It immediately reminded me of Staud; elevated but still fun and the quality matches that perception. I bought the matching skirt and have worn the set already, but I'm also loving it with jeans and linen shorts. Somehow it's become one of the more versatile pieces in my wardrobe for something that reads as a statement. If you're petite or smaller on top, size down.
