Some women wear pasties when wearing a strapless or backless dress. Some women who choose to be braless may at times wear pasties. They may wear pasties so that their nipples and areolae are not visible through sheer clothing or lingerie, or in case they experience a nipple erection.
Well Wikipedia, that's not why I wear pasties.
A couple of years ago, I got really into burlesque. I bought books on the subject, I watched videos, I sought out classes I could attend (I never actually attended a class, though I have practiced a lot in the privacy of my bedroom). I've never even been to a live burlesque show. So what is my interest in this? I think it's incredibly sexy and empowering. To me, it's different than stripping. It's comedic and sensual. It's very tongue-and-cheek. Also, from what I've seen, and know of the burlesque community, it's quite body positive, which I can definitely get behind. Here is some history: pasties were initially made in order to get past the 1920s law of performing topless. In the past few years, there has been a resurgence of burlesque and burlesque aesthetic, thus pasties have found themselves back in the limelight. I bought my first pasties soon after I became interested in burlesque. I bought them with my loan money during grad school. They are handmade from Fondapetting Designson Etsy. I bought two pairs: both are red and sparkly. One pair is heart-shaped, while the other is a simple circular shape with black tassels. They came with some double-sided adhesive (I still have trouble figuring out how to keep them on). When I opened them, I was so excited. I held the heart-shaped pair over my nipples, looked in the mirror, and thought, "Damn. These are hot." Eventually, I put the tassel-ed ones on, and tried to make them twirl like I've seen burlesque stars do--it's fucking hard.
Pasties are fun. I've put them on for special occasions, and generally receive positive feedback (minus the dude I dated off and on for two years who claimed he didn't like them). Sometimes I'll wear my pasties for myself. I'll just put them on and practice some burlesque moves. It's a nice self-love/body positive thing to do, I think.
Pasties make me feel sexy and vibrant--more sexy and vibrant than I normally feel. I get that they're not for everyone, but if you have the slightest interest, I say go for it and get yourself a pair! Or even make yourself a pair! Shake 'em for yourself or someone else--whatever makes you feel good.
I think that completes my ode to pasties.
