Once in the bathroom Karen removed her jumper. She studied her reflection for a moment but didn't spot any noticeable differences. Her eyes went to the bra. It was a no-frills article whose only purpose was support. She reached behind her back to unclasped it, then removed it completely. Her breasts had barely shifted, appearing as though they were still supported by the bra. She rose up onto the balls of her feet and dropped back down a couple times. Her breasts lagged and rebounded naturally. Satisfied that her breasts weren't statically held in place, Karen shifted her attention to the new article of clothing.
She pulled it on and returned her attention to her reflection, twisting from side to side. The sleeves were snug but comfortable. The hemline, which ended just above her jeans, was flattering while still being modest. The V-neck, however, dipped low enough that it was impossible not to show off her breasts. Karen wasn't sure how she felt about that, but she knew that her old jumper wouldn't have allowed them to observe the results of their upcoming "experiment", so with a deep breath she headed back to Jon's room.
