Question about U-boot type of uniforms

[mattesammi]

Hi guys,if you have a minute can you tell me what type of uniform (just upper part) could an U-boot crew man wear with em/nco side cap and leather trousers or leather trousers with braces?i mean they could only wear leather jacket with leather trousers or even other types of uniforms?
Thank you

I'm sure most of us here in the US are still sleeping off our Thanksgiving celebration from yesterday.

Hold tight. Someone should be around.
