with the ones that are kind of Hawaiish i would say khaki and everything else would be fine with jeans (blue or black), black shoes with white laces. because the shirts are busy go for a plain sweatshirt if your wearing one.
I'd rock a lot of em, especially the relax- tee, with a dark tone khaki jean with a white sneak. food for thought
I would say some rolled up jeans or capris with vans.
