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.

Roll on

My daughter love's the roll on and it's not too over bareing with the smell. Excellent.

Smells amazing

I always love ‘layering’ strategies. This will definitely be one that stays in our kit, alongside the undies! The roll on, not only looks cute, it smells AMAZING. My tween loves the smell and helps calm those pesky rollercoaster hormones.

MONTHLY MAGIC ROLL ON HAS REALLY HELPED MY TEEN - AMAZING STUFF

Purchased this as an extra when buying some more undies and WOW so glad I did. My teen has found this to be really helpful with cramping and feelings of sadness - perhaps it's the smell or the action of rubbing it in but don't care as she now doesn't ask for panadol.. Well done Knicked, we are the biggest fans of your amazing undies but now also love love this product too.
