I would recommend sizing up. Very tight, especially around the legs in my usual size
I use these with a cup so can't comment on the effectiveness by themselves, but with the cup they are really reliable overnight, and much less messy than pads. I haven't had a problem with leaking at all.
Pros: I love that the liner comes all the way up the back, unlike some other brands. Sturdy enough to go through the washer even though they have a cute design. I sized it by the chart and it fits me great.
Cons: I ordered two pairs of identical size, one black and one red: the black one fits me well and feels like other underwear, but the red one is really stiff, pinches, and does not feel natural. I don't know if the red is a misprint or if the red material is inherently stiffer? Also, I feel like these accumulate a bad smell just halfway through the day. I wish it would last at least a whole day without getting smelly.
Over all, I would maybe recommend them. Given how expensive they are, I was disappointed that one of the pairs didn't fit or feel great despite being the same size as the other.
I bought these to try them out and ended up buying a bundle. They are great, leak-proof and they wash well. Since getting them I have managed to save clothing and sheets from stains.
I've always struggled with using pads and tampons my whole life. When I came across these, I immediately purchased them since it's such a unique and innovative idea. Not only does it prevent leakage onto my clothes but it's also odor free even if I wear them for a full day. It's so amazing! It's very quick and easy to wash as well, I set the washing machine on cold and it's like brand new! The fabric where the crotch area is thicker and surprisedly it hasn't scrunched up like many other brands I've tried. I've been using them for the past couple of months and I will definitely not be going back to pads or tampons. Not only do they make my period days stress free but they're also really comfy and cute too!
