there are lots of different types and shapes and sizes- your body and bra also affect it.A skilled fitter is needed.I have worn a few dif types from Amonea and true Life over the years. If you happen to live southern Sydney to illawarra region i recommend Lily Bliss To You - Lily is a mobile breast prosthesis fitter and supplier and i have had much more options in prostesis and bras and service from her then i ever did at department stores They feel wierd and heavy at first but wearing one will make you feel more normal.
