Can I intentionally shrink a sweater?

I like sweaters; however, I’m your stereotypical short scrawny white kid and its hard to find ones that fit nicely.

I have one particular sweater that is 60% cotton, 40% acrylic and I’m wondering if I can wash it in such a way so as to intentionally shrink it?

I would think hot water and a clothes dryer would do it.

It probably won’t shrink evenly, though. If it’s a modern store-bought sweater, it’s probably got sewn seams - these will probably shrink in some weird way relative to the rest of the sweater. Don’t they come in extra small?

Maybe, however this was given to me a while back and is not an extra small, and I can’t return it.

Shrinking sweaters generally messes up the “feel” of the garment. After shinking they are less stretchy/flexible and less soft.

Eh. With the acrylic, it’s unlikely imho. But give it a shot. It may not shrink in a useable way though- arms more than body, etc.
