Just a thought, but if you're worried about ironing it, why not wear the shirt for a while when you're in the house coz by doing so it will iron itself out in no time. Just be sure to steer clear of hazordous liquids etc. when you have it on.
Oh wait, just a thought....you are size XXXXXXXXXL so i doubt the shirt will fit. Ah well the thought was were 😄
