Because no one else has done it for some reason.

I still don't 100% know what I'm doing with multi-outfit LORAs, so until someone else makes a better one, this is what you get.

That being said, I think it works pretty well, with plenty of variants to choose from.

You might find the default outfit is a bit overtrained compared to the others.

The main tags lui-def, lui-newyr, lui-3rd and lui-4th wok pretty well on their own, but I recommend using some supporting tags as below: (variations on separate lines)

Default outfit:

lui-def, red necktie, jacket over shoulder, fingerless gloves, thigh strap, strappy heels

yellow eyes, crosshair pupils

New Years:

lui-newyr, vertical striped kimono, blue kimono, black kimono, drill ponytail, side ponytail, hair over shoulder

long hair, hair flower

3rd Outfit:

lui-3rd, black shirt, neck ribbon, frilled shirt collar, long skirt, red skirt 

glasses, black-rimmed glasses, flat cap, low twin braids

hooded cloak, hood up

4th Outfit:

lui-4th, grey jacket 

lui-4th, grey shirt 

lui-4th, capelet 

short hair

top hat

For your own (or no) clothes:

lui-base
