Hello, I just got onto the site today. I do not own any original Andromeda props and costumes, as they were far too expensive to bid on at auction. I used to communicate long ago with fellow fans regarding the High Guard uniforms of the show. Granted, as the series wore on, it became a guessing game regarding what 'official' High Guard uniforms were. As best as I can recall, the main characters to wear High Guard uniforms were naturally:
1.) Captain Dylan Hunt (Red--'Maroon','Burgundy'[?] leather-faux leather jacket with Navy Blue leather-faux leather 'plastron' (frontal facing closure, roughly based on Imperial German Cavalry tunics) and waistband trim; matching vambraces of same materials; Khaki fly-front pants, no visible pockets; and Black U.S. Army-style leather 'Tanker' Boots) wore this in the pilot episode like a 'Service Dress' uniform. I don't recall him wearing this much after the first three or four episodes of season one.
2.) Andromeda, the Ship A.I. version (Red leather-faux leather vest with Navy Blue leather-faux leather trim; Khaki pants, no visible pockets; I cannot recall her dark boots, though they weren't 'clunky' boots so to compliment her legs-- sorry I don't mean to offend females, but the costumers went out of their way to flaunt the actress' shape, really!) wore her 'Service Dress' uniform whenever she was holographically projected aboard ship, at least for season one.
3.) Commander Gaheris Rhade (same Red & Navy jacket as Dylan, 'Nietzschean-modified' vambraces of same colors as jacket, Khaki pants, and Black Tanker boots) wore the uniform in the pilot episode, as well as flashback appearances throughout the series.
4.) Trance Gemini wore a Red and Navy jacket like Dylan's for a couple of early episodes, but as plots moved along she stopped wearing it.
As far as I can remember, that's the extent of that color uniform being worn, I suppose we could call it 'The High Guard Officer's Service Dress uniform'. OK, this is Part One of my answer for now, Gothkid1972, sorry that nobody else has answered you regarding this topic. I'll get you Part Two in a bit.
