One piece swimsuits get a bad rep because so many of them are poorly designed. They make you look fat or not toned even when you are in super shape. So, imagine how they look on someone who isn't hitting the gym every night? Right, so what you need to do is get a one piece that has been designed to fit your body correctly and accentuate curves and make your look amazing.
These are great examples of sexy one piece swimsuits. The first one has a really hot plunging neckline. The next two don't have the plunging necklines. They are great if your not interested in showing off cleavage, but still want something that is sexy. The last one has another deep plunge neckline.
