For me, I felt very uncomfortable with the silicon bra, it just feel like 2 things sticking down there and never give any "special effects". That time, when I went for my final ROM gown fitting, I tried the gown with the padding 1st. The "shape" is a bit weird coz the paddings are quite small. Then the designer cut the paddings away so that I can put on the silicon bra... well, it was a disaster! In the end, I did not wear padding, non silicon bra.
On the day of my ROM, my MUA used double sided tape and tape the top portion (just above the breasts) of my gown to my body. Like this, won't zao geng so much...
Conclusion gather.... not everyone is suitable to wear the silicon bra...
