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.

I got these for my 9 year old and is so happy with the quality. Great coverage for young bodies. My daughter loves wearing these comfy undies with confidence. We got the bundles that have with some cute little cards and bracelets. Highly recommend.
It was a surprise to notice my child was developing at 8 1/2. Being prepared with light absorbency underwear takes the fear away of my child getting her period and being overwhelmed by the arrival. She was delighted with the products, they are comfortable and meet her sensory needs.
Purchased for granddaughter ,who is turning 12 so right age to be considering periods , for at her dad’s so she doesn’t have to worry about discussing it or asking for help .
Fast delivery
So happy with my purchase for my daughter, she was very excited to receive her package. Thank you so much wonderful customer service!
My daughter loved receiving her pack of knicked undies and the little extra gifts that came in the bundle I ordered. As a 10yo with her first period, she was very panicky about when her period would come next and wearing these knickers every day has relieved her of this anxiety. I am also very appreciative of a product made specifically for girls. I highly recommended knicked undies for your daughters!!
Love these and would definitely give a five star but found the modal material has rubbed quite a bit. Only washed in cold water so not sure why this happened.
We have never had this feedback, please see our email as to how/why this may have happened and how we'd like to assist.
Great customer service , fast delivery and top notch products
Wouldn't buy my daughter any other brand
My daughter loves these. She has worn previous versions but says “these are the comfiest knickers ever” She loved the little gifts that came with the bundle and felt very special receiving the parcel. Well worth every cent.
Purchased these for my daughter who seems to be getting close to her period so that she can wear them each day in place of normal undies. A poor girl in the grade above her at school had her first period come through and stain her uniform - of course there were mean kids who made fun of her and she was just mortified. Not something you recover from easily at that age, so I don't want my girls getting caught out like that poor girl!!!
She has been wearing them for a few weeks now and has much more confidence and loves them. Thank you Knicked, we will be back to purchase more of these great quality confidence boosters! Highly recommended
I recently purchased the Pre Period Bundle for my daughter who has just turned 12, and was so impressed with the whole process. In addition to being very impressed with the quality of the underwear, it was kindly express posted free of charge.
I also bought my daughter the dance diva underwear, as she dances most days, and they are fantastic - you cannot see them through even her most light leotards and dance costumes.
Cannot recommend these enough, what an amazing product line you have created while making a tricky time so much easier for young girls. Thank you!
My daughter absolutely loves these knickers! So ouch so, that she will no longer wear anything else, ever… and that’s saying a lot for a teen who struggles to find anything comfortable (and knickers are our biggest struggle)! Thank you so much to Caro and the team for making my life that much easier!
My teenager is very happy with these undies. She is especially happy she can wear a pair all day at school and not have to worry about changing anything.
I got these for my tween twin daughters, as we are currently talking about what comes next. They are really good quality and the staff have been amazing too. Thank you! They have helped reduce anxiety of getting their period at school.
Thanks Caro, such a seamless transaction with excellent communication. My pre-teen was super excited to open her special mail and the added bonus of the little surprise was amazing. The quality of the knickers is great and I am looking forward to purchasing from this company again in the future. Feeling reassured knowing that when my daughter needs to wear these undies she will be 100% prepared
My daughters has been using knicked period undies for a few years now. Our recent bundle purchase was to add to the collection, try some of the new designs and for a size upgrade and of course supporting an Australian business. I love that they are sustainable, affordable and the quality is great, it's a no brainer! Teenagers at the best of time can be tricky to please but knicked undies sold themselves to my girls .
From the mouths of my babe's....
" they're so comformable" , " they saved me at school", " mum I need more of the period undies".
Thank you knicked, I appreciate your great service!
I bought these for my daughter who just started her first periods. They are so comfy she wears the light undies all the time. I like them so much, if they had ladies sizes, I would get myself a bundle. The extra little gifts in the bag made her feel very special and have made the whole experience exciting and wonderful rather than scary. Thanks so much.
We had already purchased Modibodi & Love Luna but heard lots of amazing things about Knicked so ordered a pair - they arrived very quickly and you can instantly see the QUALITY compared to other brands and they were a perfect fit so purchased the bundle. My tween finds these more comfy than regular undies and has the protection from LBL & discharge which gives her peace of mind. Plus we have the 2 heavy pairs ready for later on.. Believe the reviews they are so well made and super easy to wash & dry.
These are now my daughter's go-to tween undies! She liked the first order so much I ordered a second bundle as she likes to wear them daily in case of discharge. It's such a wonderful feeling as a mum to know she has that confidence to go about her normal day without embarrassment. Having her start her period at a young age with positive experiences is so important.
Thank you so much - my 11 yo is pre-period but lots of discharge. The Light Absorbancy undies are perfect for discharge and she has the Heavy ones on hand for when the big event happens. She feels so secure knowing her first period won’t be an embarrassing mess and she loves how comfy they are and are such a nice secure fit on her but not so much that they feel tight. Somehow they are just perfect! I’m very impressed and they are well worth the money. She loves the bracelet gift that came with the pack. Thank you once again - I will be purchasing again when my next daughter gets close!
Purchased for my 10 year old, they came super quick she likes the feel of them so that's a bonus as she can be funny with textures said we're comfortable, sizing good yet to actually use.
My 12yr old daughter loves the security and comfort that these knickers give her.
She has so much confidence when she wears them.
2nd lot we've got from you and my daughter loves how comfortable they are, and that she doesn't feel "weird" (her word)
I bought this bundle, plus the bags and positivity cards for my 11yo daughter who is rapidly developing and was getting very nervous about being caught out that first time. We had a very special bonding moment opening the pack together and she was thrilled with everything including the added gifts that were thrown in. Very good value for money compared to other packs I have seen. Service is fast and exceptionally friendly. Highly recommend.
My daughter loves her new underwear. She now refuses to wear anything else. Will be buying more!
I purchased the 'Pre-Period bundle - Light Absorbency' for my daughter as she is very nervous about the possibility of beginning her first menstrual cycle at school. We were both impressed with the quality of the underwear and my daughter thinks they are very comfortable to wear - she loves them!! She feels reassured and much more confident as a result - so Thank You!! The bundle was very reasonably priced, arrived within days, the pants are environmentally friendly and the little gifts were a very thoughtful touch. I am very impressed and will purchase again.
Brought these for my 11year - brilliant, easy to use, comfortable, great quality and better for the environment - A Must Have !!!
I bought these to provide by daughter with confidence that she wouldn’t be caught unprepared especially on days when dancing follows school and there is no time to get home between. They were gratefully received and have been worn already. She did comment that they feel a bit funny to start with- this will change as she gets used to them. We can’t wait for the dance ones to be back in stock.
Thanks Caro for providing options for little tweens.
