Need Some Help Deciding on an Outfit for a Wedding Poll (and nail polish)

Hey all! I'm having a hard time trying to figure out what combo I should wear for this October wedding I have this Saturday. As well as a nail polish to go with it.

I am in love with this duster (I think that's what it's called)! The color is soo beautiful and I would like to use what I have rather than going out and buying something else. So your help would be MUCH appreciated!

Just to get a picture of the wedding-- it's not very formal. It's really just a reception. My friends have a kid and have been together for like 10+ years. They are going to the courthouse to get married. We are getting together at a banquet hall for dinner, cutting the cake, dancing, etc.

There are five options below please vote to the right which would be the best combo with black pants and black heeled shoes. Leave comments if you like. Oh, and if you can think of a good nail polish to go with it (brand with name or just a color) please post in the comments.

(Please ignore my ugly-ass floor, it will be ripped out soon...hopefully)

Option 1 ~ grey shirt

Option 2~ black shirt

Option 3~ grey ruffle shirt

Option 4~ silver turtleneck

Option 5~ tan ruffle (pirate) shirt

The poll will be open until Friday night so I can have a chance to get everything ready for Saturday.

Thanks for your help! Sometimes I am not so good at this :)
