I have one made in the first season style. Mainly as it was simple.
Black military jumpsuit, patches off of ebay or other sites, all velcro adhered so I can change my rank, and a white and red turtleneck. Also had a cap made, which it wasn't until afterwards I realized they used baseball caps on the show whereas I have a military cap. Think mine looks better, to be honest. No name tag, though. Hard to find good collar patches - they keep putting the UEO insignia on the patches and it makes the rank virtually unreadable.
Love to get some props for it. Frankly I thought the first season outfit looked better than the second season, but what can you do? Though I do wish they'd had a little more distinction between commissioned and enlisted officers - as far as I can tell, the commissioned officers had collar patches and the enlisted wore their collar down. Makes it easy for me, though, if I ever wanted to do enlisted, change the shoulder patch and flip down the collar - done.
What I really love about the outfit, though, is that it's warm, so I can wear it out on Halloween and not have to worry about a jacket.
I did like the later dress uniforms, though. Particularly the detail of how they incorporated the rank stars and stripes on the collar.
