It just doesn't fit around the chest, I just don't see how this could fit anybody over 5 feet tall. I am 162 cm, 5 Ft 3, by the way.
The straps are too short and the part designed to nest the breast doesn't have enough materiel. If you wear over 34c/90b (my size), forget about it, it just won't cover your boobs, it barely covers mine.
I had to amend it to be able to wear it, I cut the straps and tie them up around my neck instead and it's fine like that. It's a bit of a shame though, I definitely don't recommend it, but I can't give it a bad review, because I am wearing it and it's quite soft and comfortable and arrived pretty fast.
