The Western dress of Pallavi, we all know by now, is of pallavi attending raghav's meeting, and surprise surprise, she'll bag/save the deal for him. This sudden participation of palavi in raghav's business is only an indicator that after the separation (emotional/physical) Pallavi will be acting pricey, giving attitude to raghav and attending his office work, as a stake holder in the business, and to give tahsan to rr and act like an independent woman.
Ofcourse, this is my take.
