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.

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 :)
