this look 
i've got a grey dress that i wore last weekend with red tights, and i think it would like great paired with purple tights like the two girls above have done.. very cool![]()
I wore a grey woolly dress with purple tights a couple of day ago. I think it's a very good look, go for it! 
snowbunny- maybe you can go for dark purple or burgandy, which will more fun than black, but still toned down for a dinner party.

) the same, but I couldn't decide between red shoes or taupe shoes! I like them both....

SnowBunny, here's a few looks with blue. I think grey's, gold & browns all work well. If you go with a red, a dark red like a rust color may be best.

Thanks for the pics, I love all those outfits, but my dress is actually black, not blue. I probably should have specified that in the original post because it does look sort of navy in the picture.
Any pictures/ideas for black?
Oops, it looked blue on my screen
. I would go with the burgandy w/black.
