The boring option

Faith had always been a little bit larger than Buffy and it seemed that carried over after the wish

She was now back to being a couple inches taller, with a slightly larger bust and a bit more muscle than Buffy Summers. The beauty mark slightly to the side of her lip was the only thing that she had that had never existed before. It seemed she was quite content if she could just have a little something over the older Slayer

The supermodel upgrade then. A Cindy Crawford to Buffy's Claudia Schiffer.
