Does your work have a goofy/strange dress code?

Tomorrow, I'm starting my orientation and training for working part-time at Macy's, where I just recently got hired for a temporary position. And I just found out that they wear ALL black. Now, I like the color black..But it's going to be weird wearing nothing BUT black to work; it's not something I'm used to doing.

My question for you is, have you ever worked at a place with a goofy and unexpected dress code? Where did you work, what was it, and how long did it take you to adapt to it?
