according to a quick search online, it says that creases are very difficult to get out of polyester. Ordinarily for other materials, I would have said just to hang it up and wait for the creases to drop out, but it may not be so easy with polyester. I'd be inclined to take it to the dry cleaners if I were you, and explain the problem. They will probably have a way around it and will be able to straighten your jacket for you.

My bathroom isnt exactly big. You mean hang it on the shower curtain rod?
Yeah or off a cupboard or something or on the back of the door. Just have it hanging somewhere and the steam from the shower will basically serve the same function as the steam button on an iron.
