Great thoughts, all!
K. Period, I think that I am maybe trying to add a little "edge" to my style, which relies heavily on modern classic. I don't like a too-sweet look as far as jewelry goes. In fact, I hadn't worn earrings in a long time but recently felt like opening up my single piercings (they hadn't closed up except for a bit at the back). I've just been wearing the same pair of earrings in them every day--small zirconia with a gold setting--because those are the only earrings I kept from my stash years ago. (They are 14K gold, which is the reason they made the cut.)
I had been thinking about double piercing for a while, but what spurred my thread was that I bought some fake silver hoops, about 1/2" dia., on Amazon and wore them yesterday in the spot where I would get a double piercing. I felt like the addition really brightened up my face and expanded my face, which tends to be long. That's what made me think that getting the symmetrical piercing might be good, as it will widen my face more. Of course, if I get tired of hoops and put something else less eye-catching in, it might not have such an effect. So honestly, the symmetry was more of a practical consideration. If what I really want is edge, asymmetry might be good. But if the asymmetry doesn't look as good on me as the symmetry, eventually I will find myself wishing that I had the symmetrical piercings. Appearance considerations will win out.
I'm going to experiment more with the hoops, maybe just putting one on instead of two, and maybe putting one up in the cartilage area. But I'll be honest and say that I'm scared of cartilage piercing because I don't want a lot of pain! Also, I have a fair amount of health problems as it is, which cause a lot of fatigue, so I want a piercing that will heal relatively quickly. I think the cartilage ones can take quite a while (?).
I also sometimes worry about it looking too young (I am 40, although I look like I'm in my 30s). But the posts on this thread didn't seem to mention that as much of a consideration. So I'm going to assume that that's not a big thing to worry about.
