In the second picture of Dasha I desaturated the yellow tones. Compare it to the picture that follows and you will see what I mean. Both dresses are the same color IRL.
The dresses on Dasha and Elise are by Cholo. Vanessa is the former Intoxicating Mix rerooted. She is wearing Ayumi's outfit. That is also Ayumi's FR2 body. Ayumi's (ugly) head is on the way to Italy.
