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 100 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 100 Day Risk Free Guarantee only applies to one pair (from any multipack) of undies within 100 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 100 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 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 100 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.
