A tankini is a 2 piece swimsuit
The tankini exists since 1990 is actually a merging of the words ' Tank top ' (camisole) and ' bikini '. It is also an intermediate form between a bikini and a full swimsuit. The upper part extends downwards (sometimes just the navel covering, sometimes up just above the hips). The advantage is that during a toilet visit you do not have to completely pull it out. In addition, many women find it more pleasant than a bikini because it conceals the feminine shapes slightly better.
