If you have a larger bust line, finding supportive swimsuits is of the utmost importance to pulling off a flattering, comfortable look at the beach. Supportive swimsuits are those styles that provide lift to keep the breasts from sagging, which not only enhances your appearance but also helps to prevent back pain and breast soreness when you're wearing a swimsuit all day long.

Here are three common features of supportive swimsuits that you can look for as you compare beachwear styles:

- Underwires - Supportive swimsuits with underwires have flexible metal or plastic U-shaped arcs positioned at the bust line. When you slip into one of these underwire supportive swimsuits, you can position your breasts to fit just over top of the two arcs. The stiffness of the metal combined with the tight fit of the supportive swimsuits lifts the bust. Many underwire supportive swimsuits are sized by bra size, helping to ensure a perfect fit through the chest.

- Soft Bra Cups - Another innovation often used in supportive swimsuits is soft bra cups. These bathing suits look similar to a bra inside with two padded cups that fit over the beasts. Some actually have a full bra built into the suit with an elastic band beneath the cups, while others feature cups alone. Both types of supportive swimsuits lift the bust line but also enhance the shape of the breasts. This makes this type of supportive swimsuits a great choice for women who may have sloped or sagging breasts due to breastfeeding, menopause or fluctuations in weight.

- Racerback Swimsuits - Racerback swimsuits are another option among supportive swimsuits and are great choices when you'll be swimming for exercise or participating in aquatic fitness classes. This style of supportive swimsuits features wide straps that are connected to a vertical band of fabric in the back. The design keeps the straps in place on the shoulders while providing lift for the bust.
