Dahlia, smirking at her with a wicke intensity, straddles behind her as she eyes the dress selected... unable-- or unwilling-- to resist the temptation, she places a hand around her narrow waist... she hasn't but a faint smile at her lips as she caressess the girl's hip...  "Perfect..." and steps back, watching.  "Put it on quickly... then do what I do."  She crosses to mid-room and kneels, in the same fashion as before, her ankles crossed behind her and her hands resting on her calves, shoulders back, breasts upthrust, head down but held high.  She quirks a brow and peeks up to watch her change, unabashedly.
