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).

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.

Everyone's period is different, and every day can feel like a mixed bag. The best thing about [pee chee cheex] is you can wear them for much longer than regular pads or tampons. They don't feel like you're carrying a brick in your undies like pads can, which is just plain uncomfortable.

We rate our undies by absorbency, with our highest absorbency styles holding up to 10 tampons worth of flow.
Feeling a bit damp? It's time to change into a fresh pair, no ifs, and, or buts.
Now, we know you might be wondering, "How many pairs do I need?" If you're not sure, play it safe and change them as often as you would a pad. That might be every two hours or every six to eight hours, depending on your flow.
Our advice? Start with a 7-pack, so you have spares on hand, and don't have to do extra laundry every night. [pee chee cheex] is here to make your period changes convenient, easy and as comfy as possible. Trust what they say, you'll never look back!
