i was on the beach recently and i saw a woman wearing a bandeau one piece swimsuit. It was really a cute swimsuit.
The only problem was that she had very large breasts.

If you have huge breasts, do not wear a bandeau, unless it has support!

This one is great. Notice how it has the support?

If there is no support,
It will give you the uni-boob.
And make your boobs sag to the ground (like the lady i saw at the beach).

Go for suits that will accentuate your chest and give you the support you need.
How many times can i say support?
Support Support Support!

If you like this suit, you can find it, and more like it here.
