As long as it looks like swim shirt they didn't say anything to us.
Not sure about the shirts but I do know that on the slides they do require swim attire, my nephew was turned away for wearing basketball shorts .
You can wear a wicker style shirt
No but they make you wear dry clothes for any non water rides
Anything presentable
You can wear anything to the wet rides but they won't let you wet or shirtless on the dry ones.
