Clothes that are a little too big, but you end up gaining weight to fit them, much like a goldfish grows to fit their tank.
I bought my boyfriend size 36 pants and they turned into goldfish clothes. First he complained they were too loose; now he says they're too tight.

None of my clothes fit any more, but if I buy new ones I know they'll just turn into goldfish clothes.
