I have used an Amoena prosthetic for 4 years - no problem as far as I am concerned although I know some in more tropical climates (I am in Melbourne!) find them a bit hot. Put in and forget. If I weren't an E cup, I'd certainly try going without, although not because the prosthesis is uncomfortable. But I'd look a bit obviously lop sided, and it would do nothing for the hang of my clothes! Personally, once I got rid of the sloshing noise of a ridiculously large seroma every time I bent over, nothing breast wise has been much of a problem! Cross fingers.
