I have a pair of Shebeest arm warmers that are awesome. They come in real women specific sizes and after having a pair of unisex PI ones that always fell down, the x small Shebeest ones are perfect. I use them a lot in spring and fall.
I have a pair of Sheila Moon knee warmers that are almost leg warmers on me. Again, love them as they are real women specific sized. I use them when I know it will warm up over 55, as opposed to knickers, where it won't.
