I don't think I've ever watched Julia on a fashion hour without hearing her say .."this is a small that I'm wearing"... or "I'm in a medium, and there's plenty of room". At the same time, I've usually been thinking to myself that she could do with going up at least one size, the creases and clinging are clues that she's in the wrong size, plus the fact that she can't move her arms without ripping something or dislocating her shoulders - simples! Self-delusion seems to be the order of the day IMO.
