evolved my Moonvine - all she wearing is her bra and pantsu LOL

Yeah, it's sad it usually comes down to stripping away some clothing to get the evolved form.
Unfortunately it happens to the majority of knight girls (the worst being debatably Southern Cross out of the ones I have) and only a few have a nicer evolved form than the normal form in my opinion.
I believe a good example of a better evolved form is Setaria or Mirabilis.

Another girl in her undies, Rose - evolved last year

Do luv Mirabilis evolved form LMAO, she was gothic dark clothing and then evolved into lighter colors

Nothing wrong with a good set of bikini armor if you ask me. Primary reason I started playing this.

LOL

Not complaining here

Though, lacking the "armor" part

I can appreciate some girl evolutions where they lose a bit of clothing like this

but moonvines evo is pretty horrible.

Obligatory Strawberry has the best evolution.

With bloomed forms it seems to go the opposite way and they get more clothing again compared to their evolved forms
