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.

Not yet used but a great first period pack in preparation of our daughter's first. She was thrilled with all the extra bits. Perfect to let her know shes special, loved & we've got her when it does happen.
My girls love them and the little gifts were amazing, love that it comes with a magnetic on care instructions as well. highly recommend
Quality, condition, value and appearance 110%.,
Great little pack to put away in preparation for the first menstrual cycle for my kid. Thanks!
I received awesome customer service. Great advice with sizes and even sent me a free one in a different size just to be sure. Will definitely keep ordering.
A fantastic and thoughtful pack that provides the practical items to manage a period and the uplifting items to show young girls that they have support and are amazing!! This pack made such a positive impact on my daughter during her first period and allowed me to give her some special and meaningful things to honour the moment. Thank you so very much for supporting young girls to navigate this time!!!!
Great present for young girls who just got their period. Helps them feel comfortable about growing up and boosts up confidence in themselves! Recommend this!
My daughter loved everything in this set and was a great way to trial some of the underwear which are all amazing!
Bought this for our 11yo daughter. Haven't used it yet but she'll be more than ready when it comes. She was a but sheepish knowing what it was for, but her eyes lit up when she saw the little heart gem. It was beautiful! This pack will come in very useful and has given her a lot of comfort and confidence when her time comes.
My daughter hasn't started her periods yet but quite a few of her friends have, and receiving this pack has made her feel more prepared for when they do.
Super fast delivery and lots of goodies
My almost 10 year older daughter loved the pack and the feel of the period undies. Winner!!
Item packaged well. Daughter does need it just yet but it's here ready for when she does.
My daughter has yet to start her period, but is close. She was so excited to receive the kit in the mail, made the experience of getting a period seem somewhat fun! The undies are too big for her and I did measure (but obviously not very well). I saw there is a great change of size offer, but given she will grow into them I will order another set a size smaller, they look
Like great quality, but obviously haven’t had a chance to test them out.
My daughter.
Loves them. So easy for her to use.
Swimmers are great too.
These undies give my 11 year old the confidence she needs when at school. The heavy absorbency undies last her a full day at school and she doesn’t need to worry about any leaking.
This pack is a lifesaver! It eases the worry of my early bloomer daughter first period experience. It was so convenient that I ordered another heavy to light period pack. Thank you for a well thought and generous free gift. I will definitely recommend this to my friends.
My daughter recently started her period and was very self-conscious and concerned about leaks. The undies are a huge success, and she has been attending school, netball and outings without any incident! She loved all the extra treats in the bag, it made her day! Thank you!
What an simple easy way to Introduce your daughter to feel confident for when she gets her first period. My daughter was so excited when she opened the pack & all the other gifts inside. This was such a positive experience. It has taken the fear away from my daughter using pads at school if that had happened. For a 50 + women i might even try a pair for myself
A friend told me about this product & i was unsure at first. I made contact asking questions & got a quick reply . Ordering was easy & quick to deliver.
My daughter is only 9 and just had her first period. I can’t recommend this pack enough. Great starter pack. She loved the bracelet, something to make her feel a little bit special
Great quality period underwear
Very happy, this is our 2nd tween staring with Knicked and both girls are very happy. Excellent quality, excellent service & the little extra's make for a nice little bonus for tweens

Loved the pack! Great for young girls!
Great little pack for my daughters first period. Love the positive quotes and how it was made that extra bit special. Also bought the bather bottoms, all pairs are true to size and my daughter said they are so comfortable! Great products!
Thank you, as a mother I was so worried that we wouldn’t be prepared that first time, my daughter we straight to school with confidence knowing she was covered.
We loved the pack we received. My daughter thought it was great and the fit perfect.
Happy to make my step daughters life easier!
Perfect pack for a period intro for my 11 year old. She can pop a pair in her school bag for a just in case.
I suggest checking sizing as I ordered a 10-12 and they are a little too big. My 11 year old is on the smaller size so I should have checked measurements.
Very thoughtful and beautifully put together, the perfect little pack to have on hand!
