I'm thinking about getting the black and white one like Janet, as well as the lavender and white one. They're super budget friendly, they look super cute, and I feel they'd likely continue to fit me as I lose more weight (and if they don't, it'd only be about $50 for both of them, so not a huge loss if I only get to wear them for one or two seasons).

So, my current bust size is 46" (I'm quite busty at any weight), and the size guide says a large is 49.4" on the bust, and a medium is 47.2", and a small is 46.1". The vest is designed to be oversized and fit loosely, as in the pictures. Do y'all think that means I should get a small because my bust size would fit within that, or should I get a medium or a large so there's some extra space and I get that looser fit? I generally wear a women's 16 or XXL in U.S. sizes. I'm truly stumped.
