The fear of wearing clothing that is the appropriate size for your body. The fear of “upsizing” your wardrobe when you gain weight and can no long fit into what you own!
10lbs of sugar in a 5lb bag! Big girls trying to squeeze into a size 16 when she knows she really wears a 22 = Upsizeitis. Even girls who wear a size 9 trying to squeeze herself into a size 6 suffer from Upsizeitis!
