There was a relieved sigh that escaped Frankie as Molly led them to her bedroom. As someone who kept their space relatively neat, but had been known to let mess slowly get out of hand the mess didn't really bother them. If their mother had seen it they would have despaired. "Nah, it's fine," they said. "I won't be long. Thanks."
As Molly left Frankie waited for the door to close and dropped the chosen clothes at the edge of the bed. They made quick work of stripping off their tight shirt, leaving the vest top over their newly acquired bra-top. One baggy t-shirt, and a jumper later they felt better. The view looking down was distinctly more comfortable. Closing their eyes Frankie took a deep breath and stuck a hand down their top, rearranging their chest a little to ease any remaining prominence. It felt so much better.
They quickly flicked a folding charm at their own clothes and took the pile out of the room and back down the hall to find Molly.
"Thank you so much, that was...a lot." They were still debating adding more goth details as a bit of armour, but for now they were okay. "I should probably explain, huh?"
