Skirt Suit With Tights What Should I Wear To My Company Party Tonight?

What should I wear to my company party tonight? - skirt suit with tights

I'm not like a dress ... But if the whole world, and perhaps should.

Possible solutions:

A short dress turtleneck sweater with black stockings and heels

or

My black suit coat

I can not decide
