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.

No more dramas at the pool!

I bought the swimsuit for my teen and she is so happy that she is able to swim any time of the month! No leaks or dramas, which is exactly what we wanted!

Fab buy for a tween/teen

This teen period surfsuit is fantastic! I'd found it hard to find anything effective and also comfortable for my 12 yo to use for school activities when she has her period (given things like tampons are not right for her at this age). This surfsuit was just perfect! She is rather fussy and also has sensory concerns but she loved the surfsuit and said it worked perfectly (even on a heavy day she said when she got out of the suit and wrung it out, there was still no leakage)! It gave her confidence and made her comfortable. It's also simple but stylish. The product also arrived very quickly.
Very happy with this purchase!
