Welcome to Knicked, Welcome to Puberty and Periods SHOP HERE
Terms & Policies
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.

*NO EXCHANGES and NO REFUNDS on these clearance products, so please choose carefully! *discontinued style or the last one in a size.
Make a splash this summer with our Teen Period Swimwear Sets, this 3-piece Summer Ocean Leaf set provides both period and sun protection with a high neck and full length sleeves but still looks great with a longer length crop top.
Set includes:
Please note: Knicked only manufactures the period swim bottoms, we purchase the additional pieces separately, therefore sizing is matched as closely as possible. Before submitting an exchange form please ensure the actual period swim briefs have been tried on for sizing.
Knicked Period Swim uses the same technology as our heavy absorbency period underwear range, with the addition of a thin layer of waterproof material to ensure nothings leaks through to the outer quick drying material, so you'll be protected EVERY DAY of your period, in and out of the water*
Our two teen models on the left are wearing a size Teen 12/14 (adult 6/8) and our Teen model on the right is wearing size 16/18 (adult size 12/14)
