i'm sure the girl is not that thick, she knows she has put on weight if she owns clothes..shopping for the sizes and her old clothes size are clear and they have no sympathy. she feels confident enough not to care or she has decided not to worry about it. either way i think mentioning it might make her insecure about her body. hints work better. straight out saying it as qwerty suggests is just cruel. it like saying you're ugly qwert get some plastic surgery.
