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.
Unlike our regular products where we provide one FREE exchange - clearance items DO NOT QUALIFY AND ALL CLEARANCE SALES ARE FINAL, so please choose carefully
Our awesome 4-piece Island Period Swim Set contains everything your daughter will need this summer at the beach, in the pool, or lazing by a beautiful river or creek. This set includes a pair of period swimmer bottoms AND a pair of regular bottoms ... this is the perfect swim set to get her through summer!
Set includes:
1 x pair of heavy absorbency swim briefs
1 x knee length, long sleeve beach wrap
1 x black string bikini top with removable mini modesty cup
1 x Non period high waisted printed bikini bottoms with adjustable ties on the sides for non-period days (though we bet you'll wear your Knicked Swim every time as they are just that comfy and sometimes periods strike when you're not expecting them!)
Please note: Knicked only manufacture the period swim bottoms, and we purchase the additional pieces separately, therefore sizing may be variable - this set is very generous).
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*
