Getting your shirt into work uncreased

A friend recently asked me a question I’d not considered:

How do you get your shirts into work uncreased?

I iron them, fold them, put them in my bag and cycle them in. Then I store a weeks worth of shirts in the office locker. I’ve found they don’t get that creased in the bag and most of the time I’m wearing a suit jacket anyway.

However, my answer is a bit boring and I feel someone might have a better solution. E.g. Wrapping shirts around a book? Special bag for carrying shirts? Never taking shirts home and instead using a Drycleaner?
