Tankini

The tankini is a swimsuit combining a tank top and a bikini bottom of the traditional bikini that generally consists of the barest minimal fabric coverage for the top and bottoms, both are reduced to triangles of cloth connected by strings.[13] The tankini is distinguished from the classic bikini by the difference in tops, the top of the tankini essentially being a tank top. The tankini top extends downward to somewhere between just above the navel and the top of the hips. The word is a combination of tank (as in tank top) and the end of the word bikini.
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, e.g. the entire suit need not be removed in order to use a lavatory. Tankinis come in a variety of styles, colors and shapes, some include features such as integrated push-up bras. A tankini for pregnant women also exists, which is divided in front exposing the navel. It is named the "peekaboo tankini".
