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

I love these! Well worth the price, sizing was perfect.

Full coverage, comfortable, no leaks

High quality, no-nonense. I've worn this pair on two different days of my period so far, one heavier and one a bit lighter. No issues with either. Washed well in between. I was between 2 sizes (S/M) and went with the larger size. I'm ~5'6, 125, pear-shaped, and I was comfortable in the M, though it is perhaps a little large, not loose enough to concern me. Also, I'd note that the fabric for the underwear and the cami are NOT the same, so it's not like a "matching" set. Due to the different fabrics, the black colors are different opacities. It doesn't bother me terribly, but I did think they might loon a bit more matchy based on the pictures.
