I saw a girl who would have been at least a size 18 wearing a bright orange tracksuit like the velour ones posted the other day. She was also doing the awesome fashion of wearing the pants under the belly overhang with the jacket creeping up over the belly. I wonder if some people look in the mirror before they leave the house.
As for elasticated pants.....I often have no choice. At my size most manufaturers have a belief that all big girls like elastic. So not true. All my work pants are elastic though because buttons and flies get uncomfortable when your having to squat and crouch all day.
