Shop Monthly

The comfiest period underwear. Period. Founded by Aiko, monthly is all about making sure the most difficult part of the month can have a little added comfort…because let’s face it… periods suck…especially if you have a hard to manage one. We’re just here to help you get comfier, cozier, and affirmed when you’re on your period. "I did not know what it was to have a hard to manage, complex period until 2022. That’s when I was diagnosed with pelvic floor dysfunction. The diagnosis made everything click: menstrual cups & tampons were causing me pain and leakage and I finally knew why. I was confused, angry, and honestly just ready to throw in the towel and grab any old pad from the period aisle… so like any rational person, I started oversharing/complaining to everyone in my circle. I realized that the people around me, no matter their unique period experience, were not completely satisfied with their products either. Whether their products were too big, small, bulky, tight, wasteful, restrictive, lacked inclusion... their experiences echoed my own. So I decided to create a new kind of period product brand — one focused on care, because myself and countless others need that the most when our periods get difficult. monthly is for those that want to change their relationship with their period, so it's more manageable, comfy, and affirming to their unique period experience." - Aiko Pickering, Founder, CEO, & HMIC (Head Menstruator in Charge) Forget the stiff, bulky, one-size-fits-all options from the period aisle.

We’re here to fill that gap. Once we’re on solid ground, we’re committing to give back by supporting period poverty initiatives in the Deep South. For now, our founder is out there pushing for real change—taking on the tampon tax, advocating for menstrual equity, supporting gender-affirming healthcare, and fighting for better access to period care. monthly isn’t just a brand; it’s a movement.
