Va Bien Response: It sounds as though you were wearing a cup size too small. If the capacity of a bra cup isn’t enough to contain a certain size bust, the bust will push the center gore and underwire away, causing the kind of bump that you experienced. I would suggest a size 48E.

Vabien Response:The strap is wide and rigid and has great power.
However, sometimes if the person is smaller in the torso the straps may need to be adjusted beyond the last adjustment possible to get the proper lift especially in a large size. Also, if the bust is real heavy it may pull so much as to move the slide slightly.
