i think unders would be better if u have a boney chest…its not just the shelf thing, its rippling too…google it, its not v nice :-s!! 1 surgeon advised overs for me but i shopped about and the guy im going with said overs would have been a disaster coz im too thin on top! Think overs r meant to be less painfull tho and quicker recovery! quite happy im getting unders tho, dnt really want the “false look” unders r more natural xx
