I'm getting obsessed with fingerless gloves these days and there are plenty to choose from if you search for fingerless gloves on Etsy. I love the idea of arm warmers too like this Tubeway Armies Arm Warmers ($25 by gayeabandon). The large colorful buckle and orange wamers are a nice splash of color in the sea of grey and black coats.
If you want to make one, there are quite a few on the CRAFT blog that I've posted about and you can find a couple here and here. These Princess Mitts above are the ones that I've been dying to make since I haven't knit cables before.
But if you can't knit or crochet, here are more picks for fingerless gloves that you can buy from crafters on Etsy:
