All dressed up & no place to go

Well, I was going to ask you to help me pick which of these outfits to wear to my husband's work holiday party. But it turns out our babysitter is sick, so I'm not going to the party (collective awwww). But I don't mind since I love hanging out with my boys! They helped me with this post. 

Outfit #1: Shades of gray

Inspired by...

Outfit #2: Spicy-colored blouse & Put-your-hand-on-my-knee Skirt

Outfit #3: Never-before-worn-but-owned-forever Dress & Cardigan
This dress & the cardigan are one small step from getting sold on ebay.

I know it's a bit like comparing apples to oranges since these outfits are so different, but on the off chance I do get to go to the party, which one should I wear?
