The lads are in uniform before they do their final strip scene. But being an American, I have no idea what kind of uniforms they are wearing. Postal mail carrier uniforms? Local police uniforms?
Any help? Thanks in advance!
It's just a cheap generic security guard uniform. As you can see on the badges on the top of the arms - "Security".
Most definitely not postman/postwomen clothes ;) Here's an couple examples:
