I know its calzedonia but impossible to found out. Also, is it push UP or not ? You "lock" the top behind your neck.

It's my swimsuit, but Im not able to know if its a push UP or not, and I have a flat breast, and I find that this top make my breast pretty so... Someone know where I Can find one liké this ? (I tried a push UP swimsuit top, but it just HORRIBLE, its not liké this one)
