The trick to that is to not care about clothes.

Good instinct for lighting here, not sure if you used the infinite lights or aimed a spot, but it looks like a fire glowing nearby in the environment. And the eyes aimed at the camera and the expression looks like she's reacting to an intruder. The props laid out makes it look like it's part of a much richer environment, until you get to that flat backdrop. Much better to use no background at all than a flat one. The effect can be mitigated if you use a camera focal length 95mm or more, but that will also flatten elements in general, and I don't think that would've supported the depth you were trying to establish here.
