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.
This is the second time I've purchased the swimwear pants, as my daughter needs next size, and smaller ones ( 3 yrs old ) look as near new, great product for young teenagers, who are not confident using tampons.
Got them today.
Thankyou Knicked, and packaging beautiful.
From a Mum who loves these products, Liza
My daughter loves her new bathers, and she's a very picky teenager! She can now happily swim at any time and with no hesitation. A great quality product. Thank you!!
The bikini bottoms and shorts fit well, but the rashie is too small.
Great product my girls love them
Great fit! Great style! Fast postage!
My Daughter loves them!
perfect
We first bought Knicked swimwear three years ago for my eldest daughter, who loves her bather bottoms....and they are still going strong!
Just recently, we bought swimwear for my youngest daughter. She is thrilled she can swim freely and have not a care in the world when it's that time of the month.
We are so happy with, not only the service, but the actual Knicked product.
What we believe sets Knicked apart from the rest, is that they have several swimwear options that have a 'heavy' flow rating. When we shopped around, we found that heavy flow rating bottoms were few and far between.
So glad we bought Knicked. We highly recommend them.
Customer service is so super amazing!! The swim brief is modern and teenriffic thank you :)
These are the best! Teen daughter feels so confident wearing these swimmers. Safe and secure fit while the style is on trend. Love these.
My daughter really liked it
My daughter loves these, looks stylish and not bulky!
Quality is great. Lovely fit and work well. 😊
These bottoms are amazing, style them up with the strings, or remove them if you are not feeling the zazz. A perfect pairing with normal swimmers!
My daughters favorite! No comparable brands in the USA in terms of style/sizing/coverage for a 12 year old girl already wearing adult sizes— thank you!
Great product Daughter loves them
The swim briefs are amazing quality and work exactly as they say, will now be buying more from this brand
Comfortable, value for money and smooth efficient transaction
Great bikini in general, can’t tell the difference between regular ones, they work!! I was so exited when I received my package and they look amazing thanks knicked.
Fantastic
My eldest daughter has been using your products for years so when my second daughter started her period at the start of summer holidays, we knew we had to purchase your swimwear for her too. The fun design, and flexibility of the three piece set was just what she needed to get back in the pool.
My daughter loves these bathers!!!
Our recent yearly family reunion was almost going to be ruined for my 11 year old until a friend told me about Knicked! They kept her comfortable and protected while swimming without any worry! Thanks for such a great product!
Works great
I had bought these for my daughters who are trying water babies all summer and they love them! I thought I would give them a go for myself and I'm so glad I did. They work amazing very comfortable and discreet, look just like regular swimwear and they work just like described.
These seemed a good price and I was keen to try some different well priced swimwear. My daughter loves them, the pattern and style and says they're so comfortable. I was skeptical with the size when I opened them, I thought they'd be way too big. But they seem to fit just right.
These swimmers are beautiful, they are elegant and look so lovely on. My daughter loves it, and all her friends ask where she got them. It would be amazing if they came with a regular bikini brief for when the period brief is not needed.
These swimming briefs are excellent. My daughter said that they were so comfy and felt just like normal undies. Knowing she could swim and enjoy time with her friends instead of missing out made a big difference to her. Ordering and delivery was fast and efficient too. Thank you for making such a great product.
Love these, an awesome two piece option with a bit of extra sun coverage for my daughter… and the added bonus of being period-safe! ⭐️
My daughter absolutely loves the high waisted brief swimwear with leak stop technology. She says they are super comfortable and she feels protected while swimming during her period. I was extremely pleased with the great customer service and the fast delivery time

I can't recommend both the product and company enough. My daughter loved the swim bottoms, they fitted well, looked great and worked. The service that the company provided me was amazing as I forgot to get express postage. They helped add it on and the swimmers arrived the next day.
