Yep, those uniforms are awesome. I dont know why they didnt make it in but they should be added. very modern looking but its not overkill. No weird rough textures, no gribbly details..its a perfect modern uniform.
Okay so the formal wear is in my opinion downright ugly. Especially for females.
Stuff I would like to see added...
Hats - Most armed forces have some manner of hearwear. In the past, Starfleet has had helmets and hats of various types. I am not recommending crazy or outlandish hats, but some sensible military hats like berets, garrisons caps, helmets, and peaked caps. And since we are explorers, how about a pith helmet.
Hair Decorations - Stuff like hair bows, ribbons, hairbands, hair clips, and the like
Uniform Decorations - Sashes like Worf and maybe other decorations like arm bands, necklaces, watches, chokers, special patches, bows
More Eyewear - Maybe I'm allergic to Retnox. Some glasses or the option to have completely white eyes and still be human like Geordi post surgey
