Use the Shower as a Steamer
This is a classic. If you don’t have a steamer or an iron, or you don’t want to use it, hang the shirt or dress on the bathroom and run the hot water. In a few minutes (or during your shower) the wrinkles will disappear.
Save your Leftovers
Use a shower cap to cover your leftovers so you can eat them later. Let’s be honest: No one uses shower caps for showering.
