the Ahh bra (or whatever the infomertial calls it) was way to tight for me - even when not having the joyful Hug. I also had a hard time just getting hte thing on when I tried on my MIL (a much larger size than I wear). I say thumbs down to the Ahh bra, IMO
As for what to waer when you have to wear your prosthetics- what about a smallish/snug cotton tank top under your dress/clothes?? Would that perhaps work or would your breast inserts fall down to your knees (talk about a "contribution" during the offering...

)
never tried any other type of these bras. I usually wear a bra and suffer for those short trips that require I dont have "headlights" showing - the majority of the time I go without anything under my shirt, but I am on the smaller size so most dont even notice. I wish you luck!!!
