I don't have any intellectual basis for it other than more formality seems to call for a stiffer, cleaner, more immaculate appearance. Is that just personal preference or not? The unstructured tuxedo I saw had a very wrinkled shoulder line when the gentleman was sitting down, which irked me. If he was wearing a corduroy jacket with an equally wrinkled shoulder, I would've ignored it, maybe even embraced the wrinkles for that look.
