I got my Lydia in fine clothes atm. The catch is you cant remove everything on her. Click her and type showinventory then remove the shield, and chestplate. You have to leave the boots/gauntlets or her script just replaces the whole thing. Every once in a while she'll revert to underware for me, but going to trade puts the fine clothes back on.
Just keep the bracers/boots in her inventory, it should allow you to replace whatever you want with the main clothing/armor slot.

So you are saying, as long as ou leave the boots (or gauntlets?), the script wont replace her equipment ? One step closer into the right direction...a fine dress and steel bracers look a bit strange together though

I did not write down the item numbers.

Click lydia
type Showinventory
type removeitem (add the steel armor number here) 100

I tried that before, it doesnt matter whether you type removeitem 1 or 100 or 99999999 ... Her script will always restore her default clothing.
This, in fact, applies to ALL NPCs....
I hope there are some flags we can set in the Creation Kit, or else we may have to make certain companions naked, just so we can dress them up with whatever we like...

Too bad that unarmored isnt available, think of all the clothing she could then wear 
My favorite companion of all time ! I suppose instead of a stolen rifle and teddy bear, this time it will be about stolen daggers and family heirlooms
