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.

Super comfortable and breathable love these will be buying more.
Great product, comfy style & fabric and undetectabke under my daughters gymnastics leotard. She is very happy and we have ordered more.
Great product, invisible under leotards and gym shorts. Super comfortable and can be worn everyday. After sales service is amazing, and fast shipping.
We received our order. They ran a little bigger than expected, but my daughter will grow into them. She doesn’t need period underwear year, but have them in her dance bag for when the time comes. Very happy with our purchase
Great undies i really like these undies they are just so comfortable just perfect for under my tights and leggings definitely no underwear lines exactly what I have been searching for . Thanks so much Knicked for a really great product
My daughter has found this new design of dance undies very comfortable and slimline. Not as bulky as the older designs. Fantastic under dancewear.
These are the real deal. They are like regular store bought no show undies but with the added protection for periods. Super comfortable, I’ll be buying more!
Such lovely undies. Both my girls use them for Dance and Gym and often wear them when they don't have their period just to feel secure. They are lovely material, very comfortable and no hem line
Great!
My daughter has tried a number of difference brands of period undies, and these are the only ones she likes to wear. She feels much more secure and confident wearing these day to day, as well as under her dance wear.
Comfortable to wear all day.
Confident they do their job.
Love these, fantastic quality, the material is so soft, no visible lines under clothes. Very comfortable
From a parent perspective these are fantastic so quick drying compared to others. My daughter loves them not being bulky, they are the only ones she will wear under her Nike Pros for cheer
MY DAUGHTER LOVES THESE AND TELLS ME THEY ARE SUPER ABSORBENT. A REAL CONFIDENCE BOOSTER.
My daughter finds them so comfortable and they are perfect for dance. I’ve already recommended them to so many people and in so many large Dance community Facebook groups. Thanks for making a great product with dancers in mind.
I bought some period underwear for my daughter. Dancing is her passion, she confirmed this style to be her favourite as the material is invisible and supports her to confidence in completing her vigorous dance schedule.
They are quick drying and look stylish and are her definitely her preferred style of underwear, within her collection.
Thank you
Even more invisable under close fitting dance gear. Great for every day too. Highly recommend
Just love these panties fit is just great and very absorbent so enjoy wearing these
Just wonderful I am so enjoying these panties
I was recommended these for my little Miss as she has just started her period. Soooooo much easier and better then when I was young. Absolutely beautiful fabric, she says super comfy. Might need to get some for me :)
These seamless dance undies are so discreet with no visible panty line at all. Perfect for under a leotard.
I should have got my regular size but went up a size as suggested. Way too big unfortunately but may try the size smaller
I bought one size which is ladies sizing of 8 (12 to 14) to try. So comfortable. But, I have to downsize to 10 to 12 because it is very loose for my size. Only for this particular seamless style. It keeps going down. I normally wear 12 to 14.. I still wear it around the house.
I bought the one with elastic 12 to 14 and fits perfectly..
These are amazing - wasn’t sure as absorbency is shorter but worked all day even in my heaviest day with the benefit of no visible Panty lines
Great period undies- not too thick and wash beautifully. Highly recommend!
Love these… we are a return buyer.
My 14 yr old daughter is very fussy with the feel of things. She said these were great and comfortable.
My daughter loved these so much, she asked to get 100 of them. No can do, but let's start with a few more. So glad she likes them, and Thankyou from a happy mum.
Amazing! She feels so much more comfortable. Thank you 🙏
