I guess my issue is they spent all the time and effort making alternate costumes/uniforms for random tasks and situation that did really require a separate uniform, like starbase, shuttle, and multiple formal ground uniforms, while neglecting to add uniforms that would have made sense like the white engineer radiation suits or the security guard armor from the TOS Movies.
Snipped as I didn't want to quote a lot of text - but if you have free time at any stage, take a search for US Navy uniforms in use right now. There's more spacey-ness in Trek's gear, but it matches up to the real world quite nicely - on a military perspective with TV, Stargates the best example. They have casual, mission and utility-ish outfits (as well as others). It's all perfectly normal and routine - and I'm glad Star Trek's finally able to replicate that reality.
I'm not aware of multiple dress uniforms
You have duty, cadet uniform, instructor uniform and dress uniform in ST 09. In ST ID there is a little more variety with the dress uniform (gray cap), Admiral's uniform (nice nod to TMP) gray utility uniform and duty uniform. The utility jumpsuit seemed to be treated similarly to camo fatigues of the US military when used for travel. Dress uniforms are not generally used for travel due to being for special occasions, usually having stricter rules as to when they are to be worn.
It depends. What we've seen in Trek so far - especially the bright white TNG movie era - feel more like the dinner dress type of things while the STID officers ground looks like the regular dress blues used for travel, official stuffs etc.
So roughly in my head compared to 'real world'.....
- The ground uniform = BDU's
- STID Formals = Dress blues
- Yorktown outfits = the jumpsuity working uniforms
....and somewhere in there we have 'space' uniforms (could be compared to the regular short-sleeve types?), the industrial wear and specialist stuffs (medical, survival etc).
Little details like registry numbers I care not about - uniforms.... way too much thought
