Ok six skirts. I'll take your word for it but I've only seen four. It could be because I'm too busy using c-points for things that I perceive as useful and I just don't find aesthetics usful in a game such as this (trust me, in other games I have hundreds of outfits ^^) where I spend most of my game time as a ship or in full body armour.
hehe ~ even more...

Being a dull person I just use the standard TNG era uniform with a tactical kit over it.
Like Janeway, I also wear the same pants for 7 years IRL
The only other 'uniform' I use is the 21st century dress for when I need to run newer Omega Force operatives through KA Ground. They need something distinctive from the background to look at or they tend to get disoriented with all the tunnels and the multi-level structure under the IMR.
I'd like to think that this is the "official" 25th Century Starfleet uniform, and can never understand why Cryptic would break immersion by allowing a large range of different uniform designs (in favour of "customisability").
I'm also working away on my Dip XP so that I can get the Diplomat uniform set.
