What to Wear: Party Outfit?

It seems that I always struggle a bit with evening outfits. My natural state of dress is covered up, so getting ready for a night out the bars goes against my instincts. Friends know that I always have to be talked out of wearing a black turtleneck and jeans before a big night on the town!

I’m having the usual troubles coming up with an outfit for the party on Friday. This is what I planning on so far:

• Party skirt – The one I own is green and a bit puffier than this white Robert Rodriguez version.
• White wrap sweater – This is probably where I go off track. Do I really need to wear a sweater inside my own, radiator-warmed apartment?
• Lace cami – Mine is more delicate than this camisole.
• Melia pumps – Gold glitter with a satin bow! I wish I had these shoes!
• Gold jewelry – These earrings and ring are from Anthropologie.

What do you think? Is this party wear for eskimos? Should I pick something like this instead?
