Size chart
Knicked Tween & Teen Period Underwear Size Guide

Please see each product page, for individual sizing.

As a general rule, please choose the same size for our period undies and period swimwear as your child's regular underwear size.

Our period underwear is designed here using Australian Child/Youth underwear guidelines. It's important to note that child sizing, also crosses over into women's sizing at our 12/14, so we have also shown this on our sizing charts (on each individual product page) to assist.

We also understand purchasing online can make judging sizing difficult and everyone has a different body shape (literally hundreds of waist & hip combinations) so we have created guides on each product page to help you choose the best fit for each product, or feel free to email our helpful team at theteam@knicked.com.au with waist & hip measurements so we can assist further.

To measure against existing underwear: use the flat lay measurement (side seam to side seam on the waistband) to compare with their current underwear.

Don't panic if you do find you've ordered the wrong size, KNICKED will happily exchange sizing and also cover the postal costs to reship (once per order) as long as underwear has been tried on over clean underwear and returned in AS NEW condition (not washed/worn free of lint/hair/marks), and packaging in original condition.

Great swimmers

Tried these and they work perfectly; feeling super confident that there weren’t going to be any leaks.

No Leaking!

My daughter has been apprehensive using any period swimwear in case they leak! But safe to say, she reported no leaks even after getting in and out of the pool a few times. Very happy teen!

SAVED SITTING OUT OF WATERPOLO EACH MONTH

My daughter plays water polo. But she would have to have a week out every month as we tried another brand and she leaked so didn't trust period swimwear - was recommend Knicked and she is now back in the pool full time with absolutely no concerns. If Knicked can save waterpolo it can save any other water based activity!
Only request is could you consider making a sport costume that is a much higher neckline than the racer, else it can cause drag in the water

Love the wide adjustable straps and coverage. My daughter dives and is always in the pool and these swimmers are the best period swimmers we’ve ever had.

Excellent product and delivery

Bought this for my 13 yr old who swims a lot. Fits well and she’s now doesn’t need to miss any classes. The delivery was quick and painless.

Quick and easy return process

Bought the wrong size initially for our daughter. But Knicked has made it suoer easy to exchange to a new size - communications were attended to promptly, new order arrived within 2 working days with return package and as soon as our return was collected (unworn and still in original packaging) a refund was processed that afternoon. Thank you for such an easy process. Will definitely buy again.

ALL DAY PROTECTION

The racer back is brilliant. Very good fit, and lasted all day period wise! Haven't tried the other one yet. It was very quick to arrive, packaging was great. My daughter loved the scrunchy and glove gift!

My Daughter Loves Them!

My 12 year old says they are very comfy and work well. The padding in the bra area works well. It's a little lower than expected but is able to be adjusted.

Amazing Product

These swimmers are amazing and have given my daughter the confidence to swim anytime she likes including competing in her school swim carnival with no leaking.

Great

It definitely held my blood on my heaviest period days, the fit is a little loose when with the straps tightened but overall it’s very very good!

Exactly what we needed

We ordered the black teen racer - size 12 for squads for my daughter. Our order was received very quickly and looks great on. Washes well and does the job perfectly. I wish this stuff was around when I was a young girl.

Leakstop racerback

I bought these for my daughter before going on holidays. They looked fabulous on! She was nervous about using them, as she couldn't quite picture how they would work, but once she wore them she was so happy. She hates tampons, so this was such a fabulous purchase! Thank you :)

Good Quality

We brought the Racer back (Adjustable) as we do a lot of swimming and boarding in the ocean.
True to size. The costume looks lovely on and feels comfy. The material seems to be high quality, and my girl feels confident in them. We have not yet tested them whilst Aunt Flow is visiting. So will review again once we test out the protection the swimwear gives

Good product but has deep neckline

The product works perfect for what it is (being a period proof swimwear).
However, I found its neckline a bit too deep :(
It's not too big of a concern because its only for a few days a month ;)
