Ironing is really only required for “dress up” clothing, casual cotton clothing is generally presentable if you wash, machine dry and fold/hang while still warm. You will have a crease and it will resolve itself in a few hours. Polyester blends also come in several utility blends like the stain free, moisture dispersing and wrinkle resistant. I’m realizing reading this thread that some people iron all of their clothing, but in my home we typically only iron our formal occasion attire (rare).
