I was in college when I learned the term “period panties.” Learning that seemingly all of my sorority sisters also had a secret stash of faded underwear bespeckled with stains, holes, stretched elastic that they hoped they’d never be caught dead in saved in the backs of their underwear drawers made me breathe a sigh of relief at the normalcy of my own indelicate delicates.

For years I, like most women, have been rotating my ugliest most tattered pairs of undies to the back of my underwear drawer and saving them for a special occasion in which they’d be called upon to serve…my period. For me, this had been a relatively predictable cycle as I relied upon these underwear to serve as backup in the event of a leak, or worse a tsunami, during this dreaded week. That is until I changed my method of birth control and my cycle changed. Most of us are familiar with the overwhelming sadness that accompanies realizing you’ve just ruined a pair of brand new, adorable underwear, when your period sneaks up on you, unexpectedly returns (seriously though, why does this happen!?), or is in some other way unusual. However, I was quickly blowing through those 5 for $27.50 “deals” as my period changed and was becoming increasingly frustrated by the emergent need to scrub my new underwear in cold water, only to have to cut my losses and relegate them to that back corner of the drawer. Soon, I had more “period panties” than I had wearable pairs. That’s when I saw a sponsored post on Facebook for THINX.

I hemmed and hawed at the idea of THINX for months, reading reviews online, texting friends to tell them I was finally going to take the plunge, and then chickening out. I was nervous. THINX were a whole new world, and I wasn’t sure what to expect. Finally, I took the plunge and went full-on THINX. I am so glad I did. I think you will be glad to try them too, and below are five things I think you should know about THINX before taking the plunge.
