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.

Perfect swimwear for young teens!

I bought these for my 13 year old daughter who had only recently got her period. We had an upcoming family holiday and she was worried she wouldn't be able to swim. The product was great quality, looked fantastic and gave her the confidence to swim. Delivery was quick and communication regarding delivery fantastic.

Bought these for my 9 year old as she has just got her period and it's so hot over here so I wanted her to carry on swimming with no worries. Super cute and work like a charm. Would highly recommend.

Great swimwea

Would be good to go with non-period-proof bottoms too with the side ties. Also need to just be careful of the ties going missing in the wash

Review on the swimwear

They fit comfy the problem is I'm an in-between 2 sizes and I haven't tried them in the water yet but I was looking for something for a cruise I'm going to go on when scheduled for period and your business got recommended to me. If I like it in the water I will definitely be purchasing more.
