So here's the reference view of Feralina's Avant Garde Outfit viewed in front and back the same way I made from Sor's Avant-Garde Outfit, so that you can see full detail in both views.

The dress is primarily white in tube style with gray lapels, fastened by three gold buttons, white detached sleeves with gray flaps on the upper arms with dark blue coloration on the forearms with a blue trim. The dress is ankle length with an opening on the front with split coattails on the back, there's dark blue coloration on the abdomen with blue accents on the lower part and a gray trims on the back, the lower part of the dress also has dark blue features along with light cyan on the front corners and back with a gray trims and bright blue on the mid-bottom sides of the dress.
