maybe this is a gross tmi but i've been in a situation where i needed to know this
if you wore something and sweated a bunch in it, like Dripping sweat. you can turn it inside out and like. air it out. for 24 hours. and the smell will disappear.....
i learned this from my corset and needed to do it for a skirt and it worked. just make sure it's not folded in on itself so all of it can dry well
