I wore black, of course, and took a friend from Andrew Melville Hall, who also attends Colgate full-time, as my date:

Alisha Sedor and I, in the New Hall Lobby
A lot of the guys, especially JSA's (Junior Semester Abroad) wore kilts:

John Slefinger and Gabe Gates
There are two kilt-hire shops in town, and apparently you can pick your color. John's is reminiscent of the Scottish flag. Normally, if you were buying a kilt, you'd research your family tartan and have the kilt be of the same pattern.
We took a bus to the hotel, where everything was decorated like we were inside the Disney movie The Little Mermaid. There were about 5 separate rooms, with bars in every room and in the lobby and hallways. One room had a swing band at first, and then a student band that was absolutely amazing. The main room had a live Ceilidh band, which is a Scottish line dance that is incredibly difficult to do if you're wearing heels (and if your date has found a partner wearing a kilt).
Apparently the whole dance cost about 18,000 pounds, which is impressive, considering only 500 people actually paid for their tickets. The other thousand were given to New Hall residents and their dates.
The highlights of the night? The student band, which was not just your normal rock band with guitars and such. They were dressed up in zebra print outfits and wigs and had a saxophone and a trumpet, and played anything you can think of. The Ceilidh is always a highlight, although I didn't get to participate - just watch.
And. Of course. The kilts.
