Flowers and rosettes have been pretty popular these past couple of seasons. I actually started out looking for a chain/belt of some sort to accessorize with my black Express dress (which I felt looked a tad too plain on its own). Everything I saw was either too gaudy or too casual... until I stumbled across this J.Crew rosette sash on eBay. It went great with my dress, almost as if it came with it ;)

I've also been wearing it more casually, as a belt with jeans for an everyday look. I had to wrap it around my waist twice because it's so long, and then simply tucked and wrapped the ends with one another.
