Pretty decent overall

Needed some new period undies so I grabbed a couple of the Sidonie Periodenunterwäsche. They got here in about 6 days, not bad. They fit okay, true to size I guess. Worked as they should, no complaints there. Felt good knowing I wasn't using disposables, you know? Just a solid experience, nothing fancy but reliable.

Reliable like always

This was my fourth order, I think. I got another 3er-Pack Set, this time with the Colette Periodenslip. Shipping was pretty quick, about 4 days to receive it in Texas. The quality is consistent with my previous purchases, which is why I keep coming back. They really hold up well after many washes and the sizing is always accurate.

Love these period panties!

I ordered the Sport-Periodenunterwäsche and a Perioden-Bikini for my upcoming vacation, and I'm so glad I did! The sport shorts felt really secure during my workout yesterday, and the bikini is surprisingly cute and functional. I was worried about leaks, but everything held up perfectly. I've tried other brands before, but Sisters Republic really impressed me with the comfort and quality. Delivery took about a week to get to Florida, which was fine. I'm definitely going to get some more of the high-waist period underwear next!

Is Sisters Republic legit? Like, are these good quality or am I gonna get some flimsy stuff that leaks after a wash? Heard some bad stories about other brands.

K Kyle Young 3 weeks ago
Totally legit! I've been using mine for months, and they hold up great. No leaks at all, even on heavy days. Definitely feels way more secure than other brands I've tried.

Yeah, they're solid. I think they even mention being Oeko-Tex certified for the fabrics, so no weird chemicals. Mine have been through tons of washes and are still good.

Hey guys, thinking of getting some period undies from Sisters Republic. How do their sizes run? I'm usually a M but sometimes brands are weird.

A Amber D. 3 weeks ago
I found them pretty true to size, honestly. Stick to what you usually wear, or maybe check their size chart if you're really on the fence. I got my usual size and it fit perfectly.

Yeah, I'd say they're true to size. I ordered my regular size and it was fine. Returns were easy though if you get it wrong.
