Get accurate measurements, we recommend you re-check your size with every purchase..

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.

I feel confident going out

Purchased another handbag while shopping on day 2 of my period. Normally, I'd rush. Not so with these panties, I felt secure. My bestie and I spent hours browsing. I never felt the need to hurry. For the first time on my period, enjoyed shopping without stress. No rushing. Just pure enjoyment.

Never turning back!

I love these so much!! These are so comfortable, haven't had any leaking, and not bulky like pads. They’re also environmentally friendly, making them so freeing to wear.

Just love them

Date nights used to make me anxoius if it was my period. Constant worry. Leaks. Loo checks. This time, I wore Peechee Cheex period undies under my dinner dress. They were perfect. The whole evening, I didn’t even think about my period once. We had a lovely meal. Enjoyed every course without stress. No last-minute changes of plans. Wish I’d found these sooner!

So far happy

These seem to work great even on the fullest days of my period. They're comfy, although I felt they rode up a little despite not having a huge bum. I was worried they'd be annoying, but they turned out to be okay.

Very absorbent. Great functional product.

This product is very functional and super absorbent with no leaks. My only mild criticism is that the bikini style could use a bit more coverage over the butt cheeks.

I love my undies

Monthly senior meetings are Stressful enough. Add my period on Day 1, and it's a nightmare. Always worrying about leaks, planning pad changes. Pee Chee Cheex changed that. Sat through our three-hour meeting. Fully focused. Confident. No sneaking off to the bathroom. It was such a relief. Didn’t think it was possible to feel this secure. But it is.

Handles my hectic day

Had a hectic day—flying interstate, client meetings, and a workout—all while on my period. Usually, I'd be juggling pads and loo breaks, but PeeChee Cheex changed that. Wore them all day, from the flight to the workout, and they held up amazing. No leaks, no discomfort. These undies made my busy days heaps easier.

Fantastic undies

I'm so glad I tried these amazing period undies. They fit great and are really comfy, much nicer than pads. They definitely offer peace of mind and keep me feeling confident that everything is under control!

Awesome product!

The modal material is super comfortable and gusset very absorbent. The only downside is that they are quite thick and can make you feel warm, but they definitely do the job. The sizing matches the size chart, which is a bit different from my usual size.

Just WOW

WOW! WOW! WOW! No more chafing, pads, or wetness. All those uncomfortable trials we ladies have to "put up with." are gone. If I could give them more stars, I definitely would!

Love them

The underwear is comfy and fits well. It provides leak protection, and I felt at ease wearing them out in public and sleeping in them, knowing I wouldn't have any unfortunate leaks in my bed

Going to def buy more pairs!

So comfortable and super absorbent. The gusset stayed "dry" and did not feel wet when they came back in contact with my body after going to the loo.

Pretty good so far

Because they are absorbent they take longer to dry but otherwise they work just as expected.

Fantastic alternative to toxic tampons

Was a bit skeptical at the beginning, I am now fully convinced by Pee Chee Cheex undies. Comfy, remain dry and are easy to wash. Would advise you to buy enough, not to have to wait that it dries during your cycle.

Great product

Good for medium and heavy days. They feel light and silky nothing like wearing pads. Only used with one cycle so far, they line dry well within 12 hours in the sun.

Feel more confident in this

Really good for overnight and "just in case". You can just wear these, confident that there'll be no surprises from your period (ie being unprepared).

Postal problem

My package got lost, and it took 15 days for customer service to send a replacement. The wait was annoying, but the undies are fantastic once they arrived.
