i dont think i can do anything wrong since the only thing you can do is to put the suit on the hanger and then clip the hanger in the only place in the garment bag.
The point is that you usually have other items in the bag (like packing cubes, shirt folders, jumpers, etc) which to on top of your suit + everything gets folded, therefore i do not see why there shouldnt be wrinkles.
I just opened the bag, which has been packed since 9am to 11pm, and the suit is not usable at all
