I think that it's ridiculous that men can't wear at least one earing per ear... I worked a year at Best Buy (A company known for their relativly strict dress code... note also the blue polo), and they even allowed one earing per ear for guys, two per ear for girls.
Funny to look back at some of the things I said before I worked at SFWoA. I did operate a ride my first day there. Also, they didn't care if people had pierced ears, tattoos, etc. I noticed at CP this year they allow spiked hair and I've seen some pretty long sideburns.
They always have that blue and red mix depending on where they work. I have a feeling those uniforms are a few years old. I really like them though. They are a lot better than those random blue shirts with the coaster on them that the SF employees have to wear this year.
