New Year's Eve - what to wear

The new year's eve is coming and with it the indecision of what party to go, what to dress and so on. This year my decision was pretty easy, I'm sick so I'm staying at home ;) end of story.
For those who are staying at home like me or go to a friends/family house wearing a super fancy gown might not be an option but that doesn't mean that you shouldn't dress up. The last night of the year asks for a little sparkle, even it's on jewelry. So this year I made two outfits suggestions, one for a party and the other for a small get-together at home.
