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 quality, work fabulously. True to size fit and decent timeframe for delivery to NZ. No comparison to any available here in NZ. Very happy.

Fantastic product

Bought these for my daughter and she loves them. She finds them comfortable and safe when swimming. Thanks

Wow! They actually work!

These were the words of my daughter after using the swimwear briefs purchased for her. She has just started working at the local pool as a swim instructor and, not being comfortable in the pool with tampons needed a solution that would work. (Previously to working at the pool, she would miss swimming when she had her period.) These briefs meant she could concentrate on her classes and keep teaching with no need to nip to the bathroom between lessons. They dry reasonably quickly although I did purchase two pairs so that one pair can be drying while the second are in use. The tassles are a nice feature, but not necessary and she was glad that these could be easily removed as she found the briefs more convenient without them.

My daughter is going through her first summer after getting her period and these bathers are a winner! They are so stylish and can mix and match with her existing tops, giving her the freedom to swim with her friends all summer long.
