Hot hot hot
Lovely looking undies that are by far more attractive and better performing than any other period undies I’ve tried. However the material was hot as hell and made my bum sweat. I still think they’re great and beautiful though.

Love these!
After a rather trying experience of accidentally pulling my IUD out with the hello cup (I know now that you’re not supposed to use them with an IUD, whoops), I was on the hunt for an alternative reusable period product that didn’t involve me going anywhere near my cervix (one day I’ll be brave enough to try the hello disc when my trauma has faded, haha). And I’m so happy I didn’t have to look far! The biggest draw to these for me is the fact you can pop them in the dryer! I don’t have to buy lots of period undies to last my entire period or worry about them not drying in time if the weather is bad for me to wear again. I can wash and dry in one night, ready for the next day. Amazing! It doesn’t hurt that they’re super cute too! I’m so glad they come in a high waisted style and the velvet on the mesh panelling is really pretty. Who knew I could look so nice in period undies?!? The only reason I’ve given them four stars is that there’s this seam between the absorbent part of the undies and the normal material that is kind of uncomfortable after a few hours of wear, as it sticks out a little and digs into my booty. But maybe I just have a too big a butt. Other than that one draw back, 10/10, do recommend.

We're sure your butt is perfect as it is! Some feedback we've had is that the "sticking out" part of the undies which you mention, which is part of the absorbent layers, softens over time and through frequent use. We're thrilled to hear that being able to use the drier is a hit for you too! Love from team Hello Period xx

Love these!
I’d been period undie curious for a long time, but never found any that really made me want to Add to Cart. I seriously love how these look, and how functional they are. They are comfy, easy care, and my new faves.
