Good but size up

I bought my size and they were too tight, especially the shorts were tight on my thighs unfortunately. Not a good feeling when I’m already so bloated. I wish I would’ve gotten two sizes up. The seams are very tight around my legs and crotch, so I just wish that wasn’t the case and that I had gotten a bigger size. Other than that the product is good but if you have a bit of a belly or a butt definitely size up. I’m normally an X and wish I would’ve gotten the 2X.


these period underwear converted me from my singular devotion to reusable pads. after changing to the copper IUD(iykyk) i found myself in desperate need of something leak proof and capable of handling HEAVY bleeding with minimal bulk. i preordered one pair of these to test them out and was hooked. i can wear them all day with no leaks (the absorbent material all the way up the front is chefs kiss)
i found myself constantly hand washing my one pair the minute i took them off so i would spend as little time as possible not wearing them. ordering more the minute i could afford it was a no brainer.

I am happy with my purchase

I bought them in a size up comfy and no leacks .


genuinely the best period undies I've ever used. most absorbent, and super comfy. probably gonna grab a few pairs of the boyshorts as I usually prefer those, but I wanted to give briefs another go. if you've never used period undies, these are a perfect option (I have tried many brands previously!) and trust me, when you experience good period undies, you will never go back. and this is coming from someone who exclusively used tampons before.

also, I got sent a freebie of the body salve at literally the most perfect time as I was struggling to find a hand creme that actually worked. I've been using it since it arrived and it is a LIFE saver, its so lovely, thank you for the freebie?! I will definitely be getting more when I run out.

Very comfortable!

The only thing is that I hope there will be bikinis in the future, the high waist can sometimes show if I'm wearing pants and bend down
