Well there’s pros and cons to both hun
Overs apparently you can feel them more, but that doesnt bother me, more prone to rippling but that can happen with unders too. And apparently they are closer together for a better cleavage.
With unders they look more natural, but are further apart because of the muscle position. Also you lose 10% of the volume, but I don’t know.
I am going with overs, but not sure whether the 400’s offered are going to be too big
as am only a 32a and size 8. What size you been offered and who is your surgeon? Have you booked your op yet? xxx
