Which color of this dress is better for Christmas office party?

I'd wear it with tights and some boots maybe and have my hair curled.

I was thinking of going red but the it's really bold and if I'd combine it with my fuschia lipstick, then it'd probably too "try hard". Or so I think.
Black is classic but common.
The blue one is nice so I added that too.

Please vote.

Red
Black
Blue
