The bikini has spawned many stylistic variations. A regular bikini is defined as a two pieces of garments that cover the groin and buttocks at the lower end and the breasts in the upper end. Some bikinis can offer a large amount of coverage, while other bikinis provide only the barest minimum. Topless variants may still be considered bikinis, although technically no longer two-piece swimsuits. Along with a variation in designs term bikini was followed by an often hilarious lexicon including the numokini (top part missing), seekini (transparent bikini), tankini (tank top, bikini bottom), camikini (camisole top and bikini bottom) and hikini. Since fashions of different centuries exist beside one another in early 21st century, though it is possible to imagine a woman combining a bikini and a 1910 bathing costume.
