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.

Great soft and stretch fabric

My daughter recently had her 1st period. We’ve had these undies on standby for 2 years! She loved them. Especially these active stretch ones. She’s a gymnast and felt confident wearing these at gym.

Great, convenient, quality product.

I wish these were around when I was just starting my period! They are great quality, convenient and my daughter says they are very comfy. She uses these on school days because they last the entire day without needing to change. When she gets home she has a shower and rinses them out, then I pop them in a wash bag and into the machine. So easy, great for the environment and at an affordable price. Definitely a winner!
