Mary picked up the vial labeled "Irish", complete with the green, white, and orange flag of its namesake country, and studied it curiously.
"I'm already white...I wonder what this will even do to me?" Mary thought. Mary was of eastern European ancestry but always had a love for Irish culture.
"Let's find out I suppose." She said, popping the cap off the vial and drinking it. Moments later, Mary felt the changes begin. "Ugghh..." she grunted as the formula in the vial began doing its work on her body. Mary braced herself against her bureau, the changes being reflected in its mirror as her body began to reshape itself.
The changes began at her feet, which became daintier, and raced her up her legs as they became more shapely and stronger looking, the sort of legs you would expect of a woman who has danced many jigs in her time. Her stomach became significantly more toned, which also had the effect of highlighting her shapely hips. Her already good-sized breasts changed little, but they now looked much more impressive on her more petite frame. Her fair skin lightened even more to become the purest of white. Her face became thinner and softer as her lips plumped and her cheeks gained a rosy complexion with just a slight hint of freckles. Her flat, shoulder length brown hair cascaded down her shoulders and her back as it curled and changed color into a vibrant red. Finally, her brown eyes slowly began to lighten until they were a brilliant green.
The changes now complete, Mary began to recover as the strange feeling subsided. She couldn't believe what she saw when she looked at herself in the mirror. Instead of seeing the face she had seen her whole life, she was now staring a beautiful Irish woman who looked like she had literally just stepped off the plane from Dublin.
"I can't believe this..." Mary said, shocking herself as her voice came out in a thick Irish brogue. "I changed my entire nationality...I'm an Irish woman!" Grinning, she began slowly turning, taking in her body's new features.
"And...I look bloody amazing!"
