I did this once when I spent a week in a hotel near company HQ and forgot to pack a rotation of shirts in my luggage. I wore my one shirt into the shower each night and shampooed/rinsed it using my body as a support form. To dry it after wringing out I left it on my upside-down laptop overnight, with a busy-wait program running on the laptop to make it nice and toasty.
