Not for large chest, even if you order your regular size.
This is super cute, and I wish it fit me, but I couldn't even zip it all the way. Everything below the chest fit fine, so if I were to order a larger size, I don't think it would fit right either. It was so tight it like split my boobs into two "boob rolls". I am usually between a medium and a large, and this was really tight. It's also a lot shinier than the pictures, but it's cute.
