I tried this on and it fit pretty nice...although it didn't look like it would, but it stretched out far enough. Just to get an idea, my chest width is 39in/C. I think it would be ok up to a 42. Anything after that might be kinda snug. The fabric is nice...very soft. The panties on the other hand...didnt fit at all. I normally wear a size 8/10 in jeans, so i think the panties are more for women who are size 4/6 or lower. Hope my description helps!
