Yess!! They are fantastic. I am a 34 A (ish) and they work in one of 2 ways:
Wear with normal push up bra to give major cleavage
Wear with bra 1 cup size bigger, to look bigger!!
I find that they only realy work with padded underwired bras or they tend to sag and you get what looks like spaniels ears!!
The only other problem is they can slip and you end up with it half hanging out of your bra, but if you find the right bra and put them in carefully they are fine.
Don't wear when drunk. I decided to have a spacehopper race when drunk at a ball, and one fell right out!!!!!!!!
HTH
