Yes. When my daughter the ballerina was dancing 40 hours a week and wore a size double zero the BMI chart said she was obese... most of us however do not carry that much muscle mass
Women's vanity sizing is beyond absurd. I've had occasion to special order size triple zero pants, and I'm just an ordinary sort of short gal. I don't understand what sizes models and starlets wear . . . quintuple zero? Negative numbers? It makes no sense anymore, and don't even get me started on consistency of sizes within and between product lines.
