Here's some sizing perspective:

I'm a sun wimp, and I love the idea of these light sleeves protecting my untan. Plus they look potentially... funky. In a good way. So when I found a color and pattern I could rock, I was all ready to purchase. But which size? I'm a six-fool plus, extra-long-armed woman who wears a size 12, so with only two sizes to choose from, it could go either way. Since these are modeled on a muscular, large-looking man, I tried the smaller size first. The top band seemed okay, maybe a teensy bit tight, but they were WAY too short. I exchanged for the L/XL and am hoping for the best, because they felt so silky and could really help when I'm gardening.
