I like the idea of Fat Lady wearing a red crop top with short sleeves and flower petal design around the neck and the end of both sleeves. With it she would wear baggy dark blue jeans and a brown and gold coloured belt. Her hair would be let down so her curls can be seen and on it I'd like to see a red head band with a ribbon. When it comes to her shoes they would be the same colour as the belt so that everything matches.
