Although I think the Fuku skirts may be longer than Starfleet Regulations allow I mean were talking about a skirt that is only about 3 inches longer than needed to keep panties from showing when standing normally. And without extra material from pleats.
The Standard colors for Starfleet Uniforms are in this next image.

Not that it has to be limited to them. But here's the entire TOS Uniform Colorcode chart I'm always fond of blues. Unfortunately the Metalics always scan darker because the scanner is designed to avoid glare.

I always use the Sciences Ensignia (though my usual RP character should use Engineering but doesn't want to get killed cause that is the ensignia of TOS Red shirts) and this next Thumbnail has all 3 along with Rank stripes that could be fun to play with as well.

All of these graphics are under copyright obviously I'm just glad Paramount and Batnam have never been petty enough to go after me for how often I post things they own.
I've just never tried drawing Fuku and well I'm not sure which if any elements could be kept without spoiling the look to either side. Any other Uniforms you would like to cross I wouldn't mind so long as there is help on this idea too.
