TMP uniforms are okay. I always thought it was a losing game.
Some scoffed at TOS uniforms as too bright and colorful, almost garish with the bold primary colors. TMP tones down the palette and then gets called out for drab, bland colors.
TMP tries to make an accurate prediction of what a closed-environment spacecraft crew would wear, then gets called out for outfitting the crew in pajamas. Just can't win.
If reality is any indication, look at what astronauts wear onboard the space station...tee-shirts and shorts, might as well be pajamas.
I guess TMP failed trying too hard to be future-accurate and not enough cinema-appealling.
