I commute daily riding 10km one way. I wear spandex bibs and jersey as they provide the needed comfort and wicking ( I sweat even when it's cooler, > 50deg F). They dry out in a control room next to my office and they're dry by the end of the day for the ride home. I don a fresh pair each day and launder on weekends.
I couldn't imagine having to use the same shorts and jersey each day. They'd either get all funky if you don't wash them daily or they wouldn't last as long with repeated washings.
Voler make excellent bike shorts at reasonable prices. I have been buying from them for years. Get on their mailing list for occasional sales.
