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.

Great bathing suit! Highly recommend!

My almost 12 year old got her period right before swimming season. I searched and found they made period bathing suits. So I said why not try it out. I am so glad I did. My daughter fits the 14/16 perfectly. I am thankful for the adjustable straps. It is great for her not to have to worry about having her period in summer and also looks super cute on! I wish these bathing suits were around when I was younger! Thank you so much! Also shipping was quicker than I expected. A bit pricey but thankful they work!

My 11 year old daughter. Likes then a lot. She is so happy she can still go swimming. Things have changed a lot since I was a young girl. It's great.

I bought the swimwear for my tween. She just wore them on a camp that was full of water activities. She said they never leaked at all and she was very confident in doing all activities. Thank you!!
