"I tried this on in a size small in store, which was definitely a good decision. It was too tight, which was unfortunate. I consider my body type to be on the smaller side (32/34 b, 110 lbs, 5'4") and the size small didn't work. It was also very sheer, which I suppose I should have expected. Definitely would not wear this alone, even if it had fit correctly. My guess is that a medium would have been more appropriate, but there weren't any to try on. I would definitely recommend trying it on person first, however, before ordering/buying it."
