For most of our styles, the most important measurement is your hip size to get the right fit. It is also useful to check your waist measurement for certain styles. Please take a look at the product description for a guide.
If you're in between sizes, we suggest sizing up (e.g. from a size 10 to 12) for ultimate comfort.
1. Place Your Feet Together
Having your feet apart can give a measurement that is actually larger than your hip area.
2. Waist
Your natural waist measurement should be taken at the narrowest part of your torso. This is where your body curves in and is often at or above your belly button.
3. Hip
Your hip measurements should be taken at the fullest part of your hips.

For first time customers, under the 60 Day Risk Free Guarantee, we'll give you an exchange for a different size (subject to availability), on your first pair (one pair) of undies that you've tried on. And by the way, you don't need to send that one back. The 60 Day Risk Free Guarantee only applies to one pair (from any multipack) of undies within 60 days of receipt.
When you get your multipack of undies we recommend washing and wearing just one pair to make sure they are right for you. That way if it doesn’t fit, the rest of your order (unopened pairs) will be eligible for an exchange (subject to availability), or a full refund.
Here's an example... Let us break it down for ya - when you get your 4-pack of undies, we recommend you try one pair on to make sure they are right for you. If that pair doesn't fit nicely, keep that one, and contact us, to return the 3 unopened pairs. Then we'll send you out a 4-pack exchange of the new size!
Our policy lasts 30 days. If 30 days have gone by since your receipt of product(s), we don't offer refunds or exchanges.
To be eligible for refunds or exchanges, the product(s) must be unopened, unwashed, unused and in the same condition that you received it. Each new pair of undies are individually packed and sealed for safe hygiene and sanitary reasons. So you must return the product(s) in the original unopened packaging.
Sale Products - No refunds/exchanges will be accepted on product(s) marked as "final sale" or "factory seconds", except for our 60 Day Risk Free Guarantee (as described above) or Faulty Items (as described below).
Our undies are made true to size, so we recommend you follow our size chart for the best fit.
We will exchange unopened, unwashed, unused undies for a different size in the same style/colour only (subject to availability).
If you change your mind, you can return product(s) within 30 days after receiving your order provided the following conditions are satisfied:
We do not accept the return of product(s) under our change-of-mind policy that are Sale, Clearance, Factory Seconds or marked as Final Sale including products in our 'We Made Heaps' category.

We get it. Trying something new, especially when it comes to period care. But with [pee chee cheex], you have nothing to worry about.
Here’s why:
With our 60 day Risk-Free Guarantee for all multipacks, you can try [pee chee cheex] with no dramas. No pressure. Try just one pair from a multipack, and if you don’t love it, return the unopened undies for a full refund.
See? No pressure at all.
And guess what? We’re adding FREE Shipping and Returns on any multipack too!
So, with nothing to lose, let’s take a look at why [pee chee cheex] multipacks are the smart choice.
Most of us spend $15 to $20 on disposables, every month—that’s over $200 a year, literally tossed away on single-use products. And that doesn’t even include the cost of replacing stained underwear and towels from leaks.
A [pee chee cheex] multipack is just under $150. So naturally, switching to a multipack pays for itself over and over again.
Not wasting feels good. But being ready for anything your vagina throws at you… that’s the game-changer.
So…
Sure, one pair might get you started, but it’s not enough for your whole period. Imagine running out mid-cycle—scrambling back to disposables? No thanks!
That’s why a multipack gives you freedom and confidence for your entire cycle—whether it’s a light day or a heavy one. Never worry about running out or having to go backwards and resort to disposables – again!
Think about it: with a multipack, you’ll always have a fresh pair ready. No more last-minute panics, no more waiting for that one pair to dry. Just grab, wear, and go.
It’s like slipping into your comfiest undies, but with built-in period protection.
When it’s this easy, can you really imagine going back?
Let’s be real: you don’t need to juggle tampons AND pads just to feel safe. [pee chee cheex] multipacks gives you full, comfortable, leak-proof protection. No more juggling multiple items. No more panty liners. Get peace of mind that comes with reliable protection, in one product.
Here’s where it gets even better: by choosing Pee Chee Cheex,
…that doesn’t stick around for centuries like disposables do. When you Switch & Save with multipacks, you’re not just saving money—you’re saving the planet. Each pair is 85% compostable and biodegradable, ensuring that when they’re done, they return to the earth instead of polluting it for generations.
Every small step adds up. Start today - choose one multipack here and join [pee chee cheex] community - making a real difference, one period at a time.
We all have people we love and care about. We want to protect, support, and do the right thing by them.
That’s why our [pee chee cheex] undies use a mix of eco-friendly fabrics and special sewing techniques that work together to create leakproof protection. The fabrics are secured inside quad barriers in a unique way experts call 'synergistic,' making each fabric and barrier more effective when combined. This ensures game-changing performance.
We design our products to actually work without adding chemical treatments for moisture management or odour control. Our designs exclude nasties like PFAS, PFOA, PFCs, Phthalates, and Volatile Organic Compounds. Additionally, our undies undergo thorough testing by a top global company to ensure quality.
We care deeply about this issue, so we set our own standards higher than the Oeko-tex Standard 100 requirements. Why? Because our undies are crafted from love, for loved ones.
We say no to adhesives in our undies. We found they can leak chemicals, lose their stickiness, and feel plasticky. Instead, we use unique sewing techniques to secure our quad barriers for long-lasting durability. Our reusable leakproof undies are comfy as, soft, flexible, and built to last as long as your favourite undies (just follow our care instructions). No undie protects like [pee chee cheex] ...or feels like them.
We've got a cracking combo to keep you feeling clean and fresh as a daisy during that time of the month. With a quick-wicking modal first layer and a super absorbent core made of bamboo fibers, our undies have built-in natural odour control. No more constantly changing pads. Say g'day to natural odour control like never before and enjoy that clean, fresh and dry feeling for longer. To find out why we use bamboo in the super absorbent core click the button.
To keep things discreet and super durable. We use not one, but two layers of modal fabric in our undie construction. The inner layer holds the absorbent gusset in place with some sneaky stitching, while the outer layer remains stitch-free. That means no visible stitching lines on the outside, so our undies look just like your everyday ones. It's all about feeling confident, comfy, and totally incognito, whether it's that time of the month or not. To find out why our modal is super comfy and sustainable click the button.
Say goodbye to elastic worries— no catching and snagging on skin, nails, or other clothes. No folding or digging into your waist. We've ditched delicate lace and high-maintenance fancy elastics. Our secret? A custom blend of materials and a special weaving technique loved by fashion designers. The [pee chee cheex] waistband handles quick changes on-the-move, no delicate threads to catch. Its unique elasticity offers a slip-free fit for all shapes. It maintains its stretch and shape even after multiple washes, and it’s so comfy you won't even feel like you're wearing it.
Our 'We Care' ethos is at the core of everything we do. It guides every step of our process, from design to sourcing to production, with genuine dedication. This unwavering commitment drives our passion for creating from love. To find out how, click the button.
