Without knowing much more about what you're looking for, I can suggest this skirt: Pleated A-Line Swing skirt which I have in brown, but is more of that trendy dark muddy pink color. There are lots of color options, with varying festive-ness. It's stretchy and comfortable and could be dressed up.

I've also seen lots of fun silver pleated skirts on ebay when I've searched "pleated midi skirt" which would be festive for a party as well.

ETA- just saw you were looking for black- which the link has black as an option, and disregard the suggestion for silver unless you are now excited about a silver skirt in which case get one and be merry :)
