Except if you look carefully at his normal outfit, you will notice he is wearing part of the standard SOLDIER uniform, he's just not wearing the shirt and shoulder pads. Instead using his black trench and specialty shoulder pads but his pants and main belts schemes is identical to Cloud's especially in the compilation's minor tweaks to the outfit.
Also, Angeal is also one of those "elite SOLDIER 1st class" and he wears the standard uniform. Not to mention there is not evidence in any of the games or Ultimania's to suggest Sephy didn't have to go through the regular ranks to get wear he is. It's is quite possible he did and just achieved 1st class in an incredibly short period of time.
All of this is just irrelevant though cause the point here is the alts don't have to be completely in line with the games mythos anyway. Bartz's outfit for instance is from a composite of different designs he has from both the game and Amano artwork. So it would not actually be a big deal for Sephy to be put in a standard SOLDIER uniform fors and giggles. In fact it would be rather refreshing since he only wears variations of his same damn outfit. Not to mention its only a matter of time before SE announces one of his DLC outfits will be his KH garb which is basically his normal outfit with a gaudy red trim to all of it...
I feel the man needs a change of pace and needs to be in something that isn't mostly black and has a trench-coat. Just like it would be fun to see Kefka dressed in something that looks like a fabric store blew up. Perhaps a tuxedo?![]()
