There are 2 major differences between a swimsuit and a bodysuit:

1) Whether there is the snap button crotch closure. As you know, one may wear a bodysuit all day long, so when she needs to go to the toilet, a snap button on crotch will be very convenient. So that most of bodysuits come with snap button design on the crotch.

2) Whethe there are bust pads or wires. Most of swimwears comes with bust pads or even wires, but normally a bodysuit will not be designed with bust pads.

Different activities involve the use of different types of clothing or garments. There are clothes for parties, for school, for the office, and there are those that are only fit to be worn at home.

There are clothes for sleeping, and there are clothes for swimming, sports, and other activities. Two similar-looking clothes items which have different uses are bathing suits and bodysuits.

A leotard is a tight-fitting, one-piece clothing garment that covers the body. It is worn by dancers, gymnasts, acrobats, athletes, and other performers. It got its name from the French acrobatic performer Jules Leotard who created it and named it the maillot.

It is usually worn with tights or shorts, and there are bodysuits with short sleeves as well as long sleeves. To wear a leotard, one has to put his legs through the neck of the garment and pull it up while inserting the arms into the sleeves.

Originally designed to be worn by males, it has evolved through the years and is now being worn mostly by girls and women who are engaged in gymnastics, skating, and other sports and performances. It is made with various materials some of which are also used for making bathing suits. In fact, bathing suit designs were influenced by bodysuits, and they look very similar although they have different functions.

Bathing suits are garments which are used when engaging in water activities such as swimming, surfing, diving, water skiing, or just plain sunbathing. They are also being used in beauty pageants to display a contestant’s figure. Unlike bodysuits, which have a distinct one-piece style, bathing suits can be a one-piece (like the leotard) or a two-piece suit (bikini or tankini). They may also be sleeveless, short-sleeved, or long-sleeved such as the wetsuit.

Bathing suits are also designed to be skin tight to provide ease in movement while in the water. The materials used in bathing suits depend on the kind of sport or water activity which the wearer is going to be engaged in. There are separate designs of bathing suits for men, women, and children. Women’s one-piece bathing suits have a bra-like lining which is not featured in bodysuits. Although the one-piece bathing suit and the leotard may look the same, bodysuits are not appropriate for swimming.
