Sleeves are perfect when you want to accessorize that little black dress or liven up a casual t-shirt. They're the answer to that New Years Eve party where you want to be sexy and keep warm. And they're great when you dont know what kind of party it'll be -- just throw a pair of sleeves in your bag, and if its the right kind of shindig, bust 'em out! Then watch heads turn, eyes bulge, and ooooohs and aaaaahs fill the air.
