Knicked Tween & Teen Period Underwear Size Guide

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 to assist.

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

As a guide we recommend purchasing the same size underwear your tween/teen now wears, for example: if your tween currently fits a child size 8/10 (in any other brand) select our 8/10 but if they wear a ladies size 10 underwear (of any brand) then select our Teen 14/16 as this will be the equivalent.  We have also provided the flat lay (side seam to side seam on the waistband) to measure against an existing pair of 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). Here is a quick link to our how to organise an exchange:  Exchange Page.

Fabulous, even when heavy flow

My daughter was very nervous about swimming at school with her period however after a thorough test in her grandparents pool she is now confident and happy to take part in swimming lessons, no matter what time of the month it is!

Amazing swim pants

I almost returned these as I thought they looked too large for my teen daughter, but I'm so glad I didn't as they are the perfect cut with the waist sitting at the belly button. My daughter wore them to her swim class on day two of her period and no leaks. These are top quality and the gusset design is superior in every way. Very happy with this purchase.

Go to swim wear

I absolutely love these swim wear! I wore them on my second heaviest day in our pool, and absolutely no leaks! It was a bit daunting to trust the process, but it really worked well. I didn't stay in the pool any longer than I would have between normal changes , although with these I definitely think I could have. The only suggestion I have is to keep going with the sizing. I can't express enough just how hard it is to get period swim wear in bigger sizes.👍
