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.

Light Protection in Super Soft Comfort
Puberty started? Discharge? Spotting? Preparing for a first period?
We've got you covered.
Our Knicked Eco Modal™ Hipster Pre-Period underwear is made from a super soft cotton-like blend with light absorbency, perfect for girls who have just started puberty. Whether it's discharge, mucus, spotting, light bladder leaks, or their period arriving sooner than expected — these offer all-day leak-proof protection in cloud-soft comfort.
💖 What Makes Them Different?
Unlike panty liners, our Eco Modal Hipster Pre-Period features:
✔ Light absorbency (5mls) - equivalent to 1 panty liner
✔ All-day leak-proof protection
✔ Super soft Eco Modal cotton-like blend
✔ White waistband (our signature for light absorbency)
✔ Feels just like ordinary knickers
✔ Hipster style for comfortable coverage
✔ Perfect for introducing the idea of periods
That means protection from discharge, spotting, light flow, or even light bladder leaks - without the waste or discomfort of panty liners.
🩰 Perfect For:
• Girls who have just started puberty
• Discharge & mucus protection
• Spotting & light flow
• Preparing for a first period
• Light days either side of a period
• Light bladder leaks (LBL)
• School days & everyday wear
🌿 Designed for Growing Girls

Our Eco Modal Hipster Pre-Period is:
• Light absorbency (5mls capacity)

Because puberty is confusing enough - protection shouldn't be.

Tip: Always ensure they have 1 pair for each day of the week (especially at school), to help them stay fresh.

A snugger fit than the play and dance style but super comfy and love the hogh protection at the back for under school uniforms.
It's quite comfy, and the gusset coverage goes all the way down the back
Bought for my daughter and so far they seem good quality and comfy. Size was initially too big and exchange process was very simple with good service.
Recently purchased these for my daughter, she loves them and says they are incredibly comfy and she can wear them all day at school with no worries of leaks.
My daughter loves these and they give her confidence and she doesn’t have to worry during the day. Highly recommend.
Above and beyond customer service. High quality product and refreshing to find a company that really listens and helps to solve a problem. You really helped me find the perfect fit for my daughter. Thank you
I have been searching for the right fit for my tiny 12 year old and you went above and beyond to help us find something that would work. I appreciate the time you took to listen and offer a solution! We will definitely be back. Thank you, from a grateful Mum
I brought these knickers for my daughter who has just started her period. Fantastic while she has her period but even better around the time of starting her period. The knickers take away the anxious feeling about having an accident (especially) at school or having to go to the bathroom all the time to check if she has started.
Well made, nice fabric and delivery was so quick.
These have made periods soooo much easier to manage for my daughter. We needed to buy a few extra pairs due to playing sport.
Great having the choice
My daughter LOVES these knickers. They're very comfortable. She also likes the other sport fabric ones. They wash well and she says they are the most comfortable compared to other brands. Great service also
I got 4 pairs of these for my almost 11 year old daughter for pre-period wear (light discharge). The fabric is very soft and the undies fit her well (size 10-12). The shipping was fast. Other brands didn't seem to have undies in children's sizes for pre-period wear, very happy we found Knicked.
My daughter loved them. Very well made and super fast delivery. Service was excellent too! Highly recommended 👌
My daughter is a very small 14 year old who got her first period very suddenly late one evening. Thankfully I had a couple of pairs of these in the cupboard (along with a few different brands) and so even though she was upset about it at least she was able to be prepared without a panic. She now wears these if she feels like something may be happening soon so she’s not taken by surprise. Out of all the different brands I have she will only wear these ones as she says they feel the most like normal underwear.
She has taken all the pairs I had to trial so now I need to get some more before her twin sister requires them.
I got these for my daughter for pre-period wear. She feels so much more secure wearing them and says they are very comfortable- just like regular underwear.
My young daughter says they are very comfy
It holds more then you would expect. Thin and feels like normal underwear. Very comfortable and no leaks. A fantastic product!
I've purchased these for my tween as she has anxiety about being caught out at school. These are a great product, well priced and arrived extremely quickly.
Great quality product. Washes well & helps keep my pre-teen’s mind at ease. Excellent service too! Thank you so much.
Bought for my tween whom has some incontinence issues. Shes so much happier and less stressed wearing these. Sizing is a tad smaller than a usual tween sizing. Would go up a size. Great product great value
Having a daughter with autism, made me very nervous come period time. Im so glad this business was recommended in an online group. My daughter has said how comfortable and soft these are. The quality is very high, and no annoying, rough seams. Customer service is also, vey high quality. Thank you.
Im so grateful a friend heard about your business and passed the details on. My daughter is loving these knckers. Will definitely be buying more. Thankyou so much
My daughter is yet to try these but have put them through their first wash and have come out extremely soft and look so comfy I'd like a pair too! Very good quality and look like they are going to do a really good job of keeping my little one secure and feeling comfortable. I also must add that the first pair we bought were too big and Caro did an amazing job getting the right size to us ASAP. Thank you Caro!!
Purchased so my 12yr old doesn't get caught without protection. Have seen other cheaper period undies but these are a cut above in quality highly recommend
Purchased these for my 11yr old to ensure she is protected from discharge and a period when it comes.. She finds them more comfy than even regular undies.. I remember the embarrassment of finding blood on my uniform and NEVER want my tween to experience this.. Caro offers the most amazing customer service I’ve ever received, she genuinely cares..
Very happy customer.
I am so glad I saw these whilst searching on google. Looking for my 11 yr old daughter as she is so stressed about getting her 1st period and being embarrased. So I showed her these undies and she immediately asked for me to buy them. My daughter has peace of mind knowing that she can wear these undies and no one will know when she gets her period. What a blessing. Thank you Knicked. I also like the idea of the bundle packs, when she actually gets her period I will be puchasing. Great idea!
I would recommend period undies to every woman - especially young girls. Knicked does exactly as it claims - 5 stars!
These are amazing !! Mum's please do your young daughters a favour and buy a few pairs of these. They are my daughters favorite underwear as so comfortable, so slim in the crotch they are undetectable and look just like funky underwear but both my daughter and I knew she would be protected if her period started and that is just what happened recently while she was at school. Life saver as she never experienced the embarrassment like I did at that age. Thank you Knicked from the bottom on my heart !!
My daughter does not have her period yet but I wanted to be ready to avoid any embarrassing situations. I bought a pair of Eco modal hipsters and a pair of heavy absorbency Knicks for my daughter to try on for fit and comfort. My daughter likes the Eco modal hipsters best as they are light and comfy.
Such a great invention!
