For my Halloween office holiday party I opted for a gothic look as I 1) had to be in the office all day and 2) was going out to celebrate my co-worker's last day so didn't want to be too much. To accompany my look, I did a gothic ombre with black and red colors (Here's my tutorial). And, of course, had to add a snake nail ring.
