I like the Admiral Uniform that Kirk wears when he's introduced. That was classy. However, the color choice for the uniforms leave much to be desired. I mean, brown, white and beige? I'm not color blind!
Also the way the uniforms are made leaves little to the imagination. Just look at the first shot of the bridge when crew members working around and that one crew member who is stretching to get things up in the ceiling. And that shot of Decker in the corridor after the Transporter accident.
