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.
Please click here for our Exchange/Refund Forms & Guidelines to organise an exchange.
Stay confident and worry-free during your period with our Active stretch underwear. Made from breathable soft micro-mesh stretchy material, these briefs provide heavy absorbency for overnight or all-day protection. No more bulky pads!
You can always pick our HEAVY & EX HEAVY (EX HEAVY only available in our ACTIVE range) ABSORBENCY PERIOD UNDERWEAR by the PINK Knicked on the waistband, which offers a high level of protection, with regular heavy holding up to 25mls the equivalent of 4 soaked regular pads or tampons and our Extra heavy absorbency period undies which are made with 5 layers of construction and provide 50mls the equivalent of 8 soaked pads or tampons and will give up to 10 hrs of protection from leaks, stains and odours.
Knicked period undies have always been and will continue to be FREE FROM NASTIES such as PUL'S (plastics) or PFAS (chemicals).
Use either all day or overnight without the need for bulky soggy pads or uncomfortable tampons.
Cooling lightweight stretch material in our brief style.
