I am designing a line of mens swim shorts. I notice that many of the high end brands such as Orlebar Brown, Dolce and Gabanna, Paul Smith are using nylon instead of polyester. I find nylon to be rigid and easily wrinkled. I prefer to use polyester like the board short companies eg Quiksilver. Can you please advise what is the advantage of using nylon as really all the high end designer brands are using it. Is there any consumer perception that nylon is better?
