Pressing widebacks is a brute!
Yes, you could send it to a dry cleaners. Just ask for it to be pressed.
Best to check your price first.
Some long armers will press it for you ... of course, for a fee!
One good thing, if you can get the LA'er to do it for you, then you don't have to worry about it getting wrinkled after pressing and before you deliver.
Good Luck!
