Underwire bikini tops are fantastic for both those who are a little-smaller-on-top and those who are a bit busty on top. Underwire bikini tops both enhance what you have and offer added support.
An underwire bikini top, especially one in a demi cut, can really enhance the chest of a woman with a smaller breast size. A demi cut resembles a bra, but it is not a full cup. A demi cup with a little bit of padding can offer a woman the cleavage she never knew she had! If you are smaller on top, it is also a good idea to look for swimsuits that offer texture like ruffles. It is also good to wear a suit with an interesting pattern - something that will deflect attention away from your bust.
