Helm From Nikke:Goddess of Victory.

Works pretty well with most models I tried (AOM, Anything and Corneo's 7th Heaven) with the OrangeMix VAE

Trained on her default skin and her evening gown skin, ranges between 0.5 - 0.7

Default - military uniform, white skirt, epaulettes, buttons, belt, medal, white gloves, sword, jacket, jacket on shoulders, high heels, hat

Dress - feather hair ornament, white dress, evening dress, shawl, thigh, necklace, jewellery, gold trim, bracelets, armlet, thigh strap, strappy heels
