I started wearing wigs when I was in my 30's. I just got tired of dealing with my hair, especially when I got up late for work. One day I went in the store looking for another wig and the proprietor asked me why on earth I needed a wig with all the hair I had on my head.

After awhile, I got tired of wearing them.
My sister and I started having thinning hair on top a few years ago. Leaving it natural and cutting it really short solved the problem for me, not to mention I cover my hair in public anyway. My sister bought a very nice wig and I think it enhanced her appearance. I've seen cute wigs and thought about trying them, but there's no point. I think if you feel they would do something for your spirit you should go ahead and do it Fanci.
Heck, go crazy. Get a couple and you can change your hairstyle in an instant.
