I'm a 38D, ordered the white in XL. the material is really thick, so it may not be the best summer shirt - but it also isn't see-through. I usually size up in shirts but bought my normal size, and it is way too fitted. the opening comes up higher on my back and it felt tight across my shoulders (which are broad). I like the concept, though, so I'm going to order a few sizes up and cross my fingers. I didn't have any problem untieing and adjusting that strap, btw.
