Alternatively Itsy Bitsy Teeny Weeny Bikini, but I think a unisex title is better.
A swimsuit noted in-universe for its extreme brevity.
While Moral Guardians
have been complaining about swimsuits showing too much skin as long as there have been swimsuits, this trope really took off after the introduction of the bikini.
To qualify, a swimsuit must be described or reacted to in terms of how small it is, or how much it shows. For example, if the text claims it's "two postage stamps and a thick string", or onlookers are shown having their eyes bug out.
