Fingerless gloves are worthless as gloves. Their purpose is purely decorative, as they fail to do all the things you need gloves for. They won't keep your hands warm in the cold air, they won't keep your fingerprints out of crime scenes, and they won't conceal your badly chipping manicure.
I purchased these a couple years ago against my better judgement. I saw them, I loved them and then I put them down because I realized how rarely I would wear them. But then Jessica happened to blog about them, and as I'm sure you know, once someone else blogs about something, you want it all the more.
So I went back and got them; they were $20, and I'm currently averaging $10 a wear.
