That's very difficult to do. The way most jackets are cut, if you try to shrink it, it will shorten, but the width won't change. If you want the sleeves to be tighter, you would be better off altering the jacket to provide whatever fit you wish. It isn't that difficult to do.
Reply:wash it in hot water and dry it in high heat
Reply:i do not think it can be done. most cotton items are made from preshrunk cotton. and polyester does not shrink but compress and sort of bubble..


i think it would be best to take it to a seamstress and have it altered.
