While the bikini has certainly had its share of criticism, it also serves as a reminder of the beauty of a healthy, toned physique in the U.S. and around the world.

According to Allure magazine, a recent poll conducted by Mamma Mio Skincare found that just 30 percent of American women say they feel confident wearing a body-revealing bikini bathing suit.

The "Summer Confidence" survey, which polled 8,000 women in the U.S. and the UK, found that while Americans are overall more confident about how their bodies look, there are some things that many would change if they had the opportunity.

The survey found that 10 percent of women feel that they need breast augmentation surgery to enhance their bodies.

This surgery, which involves the placement of an implant behind each breast to increase volume and enhance shape, has been the most common cosmetic surgical procedure for the past three years, according to the American Society for Aesthetic Plastic Surgery (ASAPS).

Others on the other side of the spectrum opt for breast reduction surgery to look their best in a bikini. Those who undergo the surgery often seek to have their breasts be more proportional to the rest of their bodies. In addition, breast reduction surgery often makes a dramatic change in appearance as well as physical comfort, according to ASAPS.

A separate survey conducted by Allure magazine found 35 percent of people would chose their stomachs as the one area of their bodies that they would change if they could. Abdominoplasty - or "tummy tuck" surgery, as it's more commonly known - firms and smoothes the abdomen by removing excess abdominal skin.

According to ASAPS, tummy tuck surgery was the fourth most common surgical procedure undergone by patients during 2010, with more than 144,900 procedures completed. 

While some may opt to wear body slimmers, such as Spanx, to keep their bellies in check while they're clothed, a tummy tuck is often the best option for those who want their midsection to look perfect while wearing a bikini.
