The monokini

The monokini was originally a panties with braces revealing the breasts of women, designed in the mid-1950s and launched in the early 1960s by Rudi Gernreich. In its modern form, the monokini is a bathing slip worn leaving the breasts uncovered. The expression to make the monokini means to have only the panties of the swimsuit and leave his chest in the air. Making a monokini on the beach avoids tanning marks on the skin.

The term may also refer to the bikini panties of 1946 which is also sometimes called unikini.
