zipper bikini

A bikini that features zippers, usually cutting across the middle of the fabric over the wearer's breasts or crotch. Often worn by Eimi from Blue Archive, whose default outfit features a black zipper bikini top. Sometimes unzipped, where it may resemble nippleless clothes or a crotchless bikini. May feature a prominent zipper pull tab. If the top has zippers that cross the wearer's breasts, include breast zipper, and if the bottom has a visible zipper over the crotch, include crotch zipper (regardless if they are unzipped or not).
