i'm 17 and my mom got me these for our hawaii trip. i finally went in the ocean instead of sitting on the towel pretending i was reading.

the scalloped trim. the satin ties. it doesn't look like a 'period product' AT ALL. that's the whole thing.

i bought one as a backup for my cup on a 4-day cruise. it became my main. zero leaks. wore the same set three days in a row (washed nightly).

my daughter said 'i actually want to wear this' which is the first time she's ever said that about anything period-related. pikini wins.

i've tried other period swimwear forever but those options are so basic. pikini is the first period swim that looks like something i'd actually buy.

wore mine at a pool party feeling completely normal. nobody knew. that's the whole pitch and they delivered.

fit is perfect. ordered my usual bikini size and it was right on. ties are sturdy, not flimsy like cheap swim.

honest review, day 1 of a heavy cycle is still a tampon day for me. but day 2 onward, this is all i wear. exactly what they say it is.

sent a photo to my group chat and three of them ordered the same day. summer of pikini.

the lining is genuinely thin. i was sceptical it would actually work but it does. swim, rinse, hang dry, repeat.
