It is false advertisement what I care more about is to know if you're putting the bra on because you just wanna look more special for an occasion or because you are insecure and not happy with your natural look. If you just wanna have some fun, great; if you're insecure, I am not happy with that.
I asked my guy friend the same thing and he said push up bras were like potato chip bags. You buy one thinking you're getting a whole bag, but half of it when opened is air. Kinda disappointing. But that being said, I think guys will just appreciate even seeing your breasts in general and will love them any way they come. If you feel confident and sexy in a push up bra, then rock it!
