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 pads, no tampons, no worries. Just you and the water."

How to wear:
These aren't your average undies - pull them on, then up high at the sides so they sit snugly and low under the belly for the best protection.
Care tip:
Wash before first use. Each pair comes in a reusable, waterproof, and odour-proof wet bag – perfect for storing your BFFs in your bag or when they're wet, waiting for a wash. Less waste, more wow.
No leaks. No worries. No limits. Just freedom.

Our teen model prefers a Teen 14/16 (adult 10) but could also wear a Teen 12/14 (adult 6/8).
Please use the flatlay measurements to compare to another brand or existing pair to select the correct fit and if between sizes or very tall we recommend sizing up.
