The tankini is a bathing suit combining a tank top, mostly made of spandex-and-cotton or Lycra-and-nylon, and a bikini bottom introduced in the late 1990s. This type of swimwear is considered by some to provide modesty closer to a one-piece suit with the convenience of a two-piece suit, as the entire suit need not be removed in order to use a toilet.
The triangle top is the most common and popular bikini top. Triangle tops are just that – triangle shaped cups strung onto thin straps. While triangle tops tie around the neck as halter tops do, triangle tops tend to offer less coverage and support, giving you a sexy beach style.
