I have started to see elastic headbands in the stores now that are wider up at the top, where they go across your hair, and thin at the bottom where they go under your hair at the nape, rather than being one size all the way around. And they're being made in cool colors and patterns, too. I'll be darned if I can find a link to anything like it online right now, but keep an eye out anywhere you can find a decent selection of hair accessories, and you'll see what I mean.
