What to wear tonight?

I have no clue of how we are spending this New Years Eve evening. Therefore I don't know what to wear. I've got four outfits, two in case we want to go glam, and another two if we are going really comfy and relaxed.

The two dresses are the same in terms of color, but they are both different in style. If we go glam I am leaning towards the one on the right, its like a halterneck dress. Both have a bow that you tie in the back.

The bottom two I was thinking (of course with either leggings or denim) the one to the left hand side. You cant really see the color, its more of a charcoal grey. I might not even go with any of these, who knows. I'll give you guys and update on what I end up wearing.

Hope everyone has a great evening and an incredible New Year!
