Knicked Tween & Teen Period Underwear Size Guide

Please see each product page, for individual sizing.

As a general rule, please choose the same size for our period undies and period swimwear as your child's regular underwear size.

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 (on each individual product page) to assist.

We also understand purchasing online can make judging sizing difficult and everyone has a different body shape (literally hundreds of waist & hip combinations) so we have created guides on each product page to help you choose the best fit for each product, or feel free to email our helpful team at theteam@knicked.com.au with waist & hip measurements so we can assist further.

To measure against existing underwear: use the flat lay measurement (side seam to side seam on the waistband) to compare with their current 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), and packaging in original condition.

Please click here for our Exchange/Refund Forms & Guidelines to organise an exchange.

Great purchase experience

We ordered the modal hipster originally and my daughter wasn't happy with the fit. Knicked made it super easy to exchange and we got the active stretch in the same size. She hasn't started her period yet but we're feeling more confident and prepared!

Great undies. I wish they would cover more bottom, they fit perfectly except for the bum coverage. Daughter finds they ride up.

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.
