Carmilla Black / Thassanee Rappaccini / Scorpion (Marvel Comics):
The last one is a "Neo-Symbiote" costume she had for a handful of pages in one comic.
Alita ( Battle Angel ) / Gally (GUNNM):
Priss Asagiri (Bubblegum Crisis)
Samus Aran (Metroid series)
That's every suit from the main series, including her "civilian" clothes from some of the endings and the "justin bailey" costume, plus Phazon Suit from Prime series. I forgot to save the Fully Powered Suit and Varia Suit with the Victorian Decor aura seen on Phazon and Gravity suits.
Vampirella
First is as close to the "classic" look as I could get (no good shoulderless body thong, Labeaux kind of forced me to use gloves), second is a trenchcoat variation seen in Vengeance Of Vampirella, last one is a redesign from the 2010 series
Purgatori (Chaos Comics)
The second and third design may only have appeared infrequently (or even only on covers)
A bunch of one-offs: Rayne (BloodRayne), Duke Nukem, John Constantine (Hellblazer), Doktor Sleepless, Faith Connors (Mirror's Edge), Guyver 01, Maximillia "Maxima" Leander (Grrl Power), Michael Jackson (Smooth Criminal music video), Superior Spider-Man, Spider Jerusalem (Transmetropolitan)
