Clothing shrinks in the dryer... You can put your clothes in the washer in hot or cold water and nothing will happen to them, that why I only hang-dry my clothing!
I don't go out and try stuff on and then buy them cause I know they're gonna shrink into the size I need
"Oh, I bought a XXL cause when I wash it it will become a small!"
Actually, if they are old "hoodies", you won't be able to shrink them. You have a better chance of getting raped in the ass by a feeble senior citizen.
They are maxed out in shrunkeness, if thats a word.
