YES. Although, normally I like to coordinate (it's more original) I think that mis matched gloves, hat and scarves (esp when it's a solid color) is a sloppy look.
I have a Coach Optic muffler which is mainly black but has grey and white, so I wear my grey gloves and hat from Benetton, there is also a scarf from the same line. Also I got a peacock scarf, hat and gloves from Benetton, I think it's so chic when it's freezing to have a fun but not crazy color to spice things up. Right now I want a black basketweave muffler from H&M, it's from the women's collection so it might be too small, gotta try it on.
