Nice Butt
The new undies do have nice padding and in loose fitting pants will help fill in the extra material. I guess my butt is already fairly round so not a huge change. Still a nice product.
Trunks
Love the trunks, got a L , but I should have ordered M.. Next order will be M
Size Difficult
I like the effect, it does add where it should. Unfortunately I seem to have ordered to big, taking into account the one RB I have, that I found too small and the advice on the site to rather take a bit bigger. So I don't know if it is my anatomy or the product. I will order one size smaller again to give it another try.
