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.

Fits well

The bikini brief looked bigger than in the picture but fitted really well and have good coverage whilst still sitting underneath the short

What a fantastic set

Our daughter is absolutely in love with this. The ability to wear a swimming costume during certain times of the month without having to change to something ugly and looking like she’s wearing a nappy is unbelievable. The construction of these garments is fantastic and I would highly recommend these products.

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
