Don’t iron work shirts because I wear jumpers over them. Although I’ve got a couple of shirts that could do with it so I just run my wife’s hair straighteners over the collars and bingo.
I have to iron jeans occasionally because I keep them in a drawer, not hanging up, and if they’ve just been washed they need an iron.
Same as the above with t-shirts.
All other shirts I wear casually - 100% ironed every time (EXCEPT the 2 I have that come up just fine by hanging them in the shower when I have one in the morning)
