She arched her brows at the bag, then went to go poke through it. How often this the Doctor actually invite her to go looking through his belongings. Not that she usually waited for an invitation, but still.

She was tempted to stick with what she had, but then a smile curled at her lips, a delicious idea forming. She started pulling clothes of his over her own, a few quick adjustments here and there as needed. Nothing that would last long, but that would hold well enough for now, which was all that was needed.

Soon she was in black trousers, a white button down shirt half unbuttoned over the jumpsuit. She considered the waistcoat, then smirking, pulled it on, buttoning it just so, making it make her seem that much more impressive, then the black jacket. That done, she began stashing her stuff in the waistband, pockets, and tucked into her shoes. She had to take the boots from the suit, sadly. Not much for choices, there. But still.

She walked over to him, it was cute how hard he was working to...not... look. "Well, I must say, I like the style." Which of course, was her way of saying "I wear it better" without saying that at all.
