Fakte ne. Ĝi nomiĝas laŭ Bikini Atolo en la Pacifiko.

El http://en.wikipedia.org/wiki/Bikini:

The bikini, which shocked when it appeared on French beaches in 1947, 
dates back to antiquity, in Çatalhöyük and the Greco-Roman world. The 
modern bikini was invented by French engineer Louis Réard in 1946. He 
named it after Bikini Atoll in the Pacific, the site of the Operation 
Crossroads nuclear weapon tests in July that year. The reasoning was 
that the burst of excitement created by it would be like a nuclear 
device. The monokini, a bikini variant, is a back formation from bikini, 
interpreting the first syllable as the Latin prefix bi- meaning "two" or 
"doubled", and substituting for it mono- meaning "one". Jacques Heim 
called his bikini precursor the Atome, named for its size, and Louis 
Réard claimed to have "split the Atome" to make it smaller.

Mallonge, la inventinto komparis la bikinon al nuklea eksplodo, kiel 
tiuj kiuj okazis en sur Bikini Atoll. La konkurenca bankostumo estis la 
unupeca "Atome" ("atomo" en la franca); do "bikini" duigis (dividis?) la 
atomon.
