I can tolerate, but do not like the Star Trek II -VI uniforms.
They don't look like a step forward from the TOS uniforms...if anything, a step back. Like you might accept the crew of the Horizon or Valiant wearing those...but not a post 5-Year Mission Starfleet.
I like the TMP uniforms, but I would have made them one piece and kept the colors from TOS. I would not have had that useless and unused bio-monitor on the belly either.
I would have made them look more like the Admiral's uniform, but one piece..and the dark gray would have been either blue, red or gold...maybe use the green Kirk wore during TOS season two as part of an Admiral's uniform.
