for the girls who don't trust tampons
the summer you stop sitting out.
period-proof bikinis you'd actually wear. five hidden layers. no tampon. no pad. no thinking about it.
⭐⭐⭐⭐⭐ 1,200+ happy customers · pfas-free · holds 3 tampons' worth
pikini is for you if...
1. you hate wing tan marks.
2. you don't like tampons.
3. you fear the leak.
for years, you've sat out countless pool and beach days. 🏖️
the dread before every trip. checking your bikini bottoms every five minutes. praying nothing leaks through onto someone's white towel.
and the worst part? there's no good option.
tampons are scary — or just uncomfortable. (your friends agree, even if no one says it out loud.)
pads do nothing the second you hit water.
and every period-proof swimsuit you can find looks clinical. like sportswear. like the opposite of a bikini you'd actually wear in front of your friends.
we get it. we built pikini because we lived it.
so we made one.
the bikini that has you, all month. 🌸
soft on top. five layers underneath.
no tampon. no pad. no leaking. no thinking about it.
just the kind of bikini you'd buy even without the technology.
what makes pikini work. 🧵
five layers most period bikinis don't bother with.
sewn so carefully you'd never know they were there.
- 1
scalloped outer
the part you see.
- 2
moisture-wicking
pulls everything down and away.
- 3
absorbent core
holds up to 3 tampons' worth.
- 4
leak guard
the line nothing crosses.
- 5
soft inner
feels like nothing.
the wet test. 💧
we poured the equivalent of 3 tampons' worth of liquid on a regular bikini.
then we did it again on a pikini.

"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."

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

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

why we made this. 💌
i'm char. when i was sixteen, i missed my own pool party — because i got my period that morning and didn't trust anything i owned to get me through the day. i sat inside, in a towel, while everyone else swam.
i never forgot that feeling.
so i made the bikini i wished i'd had. period-proof. tampon-free. and made to be seen.
find your glow. ✿

honest answers. 💬
how does pikini actually work?
five hidden layers in the gusset hold the equivalent of up to 3 tampons' worth of liquid. no tampon, no pad, no nervous bathroom checks. soft on top, engineered underneath.
how heavy of a flow can it handle?
light to medium flow days. for heavy flow days we recommend pairing with a tampon or cup as backup. (not because pikini fails — because we'd rather under-promise.)
is it pfas-free?
yes. third-party lab tested clean before every production run. lab certificate available on request.
how do i wash it?
rinse in cold water immediately after wearing. machine wash cold in a mesh bag (we include one free with orders over $200). hang dry — never tumble.
what if it doesn't fit?
first-fit promise — 14-day exchange for unworn product. we cover the swap.
what if i don't love it?
30-day money-back guarantee. wear it, swim in it, and if it doesn't change how you swim, we'll refund you.
how long until it ships?
3 business day lead time from vancouver, then 5-7 days in transit. free shipping. expedited available at checkout.
can teens wear it?
yes — pikini was made for the girls who don't trust tampons. perfect first-period-friendly swimwear.
