I have this top in two colors, and yes it is wrinkly. I also don't iron; I spray with a mister. When an item comes out of the washer, I spray pretty heavily before it goes in the dryer and then remove it and hang it when it is warm, very damp, and at least most of the wrinkles have come out. I may also spray again and smooth/stretch out the wrinkles. I also spray after I have worn it so I can wear it a second time assuming it is still acceptably clean. I never ever put on a wrinkly item, but at the same time I rarely set an iron to anything -- like maybe four times a year.
I wish this top didn't wrinkle so much, and I will stop at two colors. What I really like is the softness like jammies.
