The Difference Between Bikini Swimsuit And Underwear

First of all, in terms of materials: 80% of the conventional bikini swimsuit fabric is nylon and 20% is spandex. The more spandex, the better the elasticity and the greater the drainage coefficient! The lining is 90% polyester and 10% spandex; while the bra fabric is 85% nylon and 15% spandex. The fabric is not as good as bikini. Because the spandex content is low, the elasticity is worse. The bra lining is 70-80% polyester and 30-20% cotton. This is much more comfortable than the lining of the swimsuit. Moreover, because bras are worn for a long time, the higher the cotton content, the less static electricity, the better for the chest. Therefore, the bra can only be worn inside, but the bikini can be worn inside as a bra or as a swimsuit outside.

Secondly, underwear will become transparent when water enters, but swimsuits will not. The fabric of swimsuits is relatively smooth and has great elasticity, which is beneficial to reduce resistance when swimming. Moreover, it will not be washed away by water when swimming, and the water has great resistance. When wearing underwear as a swimsuit, it will definitely run out and is not suitable for swimming.
