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.

Loved it!

Wore the bottoms for 10 days straight at the beach and I absolutely loved them’ They held up super well and made me feel secure. The top was a little big, wish it was adjustable around the underbust or able to select alternating sizes but otherwise amazing and super cute!

Incredible! Fantastic! Highly recommend

Thank you! Honestly, thank you!
I purchased the 4 piece swimwear set that included the heavy period swim briefs for my daughter and I can honestly say that I am SO happy I did. Apart from the set being beautiful, comfortable and without a trace that they are anything other than normal swim briefs, they 100% work!!
My Daughter although still young (12) suffers a very heavy flow between days 2 and 4 of her cycle. Being summer holidays my daughter and her friends planned a day out at the water park only to wake up the day before going with her period, meaning that yep... day 1 of heavy flow was going to hit right at the same time. We had the swim briefs but had not tested them yet so both my daughter and I were very nervous. Turns out we had absolutely nothing to worry about! She spent 9 hours at the water park with no embarrassing moments! She took herself to the bathrooms throughout the day to rinse her briefs and keep on swimming. It was amazing. My daughter even said how relaxed she was and how her anxiety had gone away. Thank you so much!
(**Note: we did notice some light transfer from swim briefs and towel when she sat down, but we solved that problem with a dark coloured beach towel).

Pant sizing was a lot smaller than the rest of the swimsuit, did not fit
