I'm with Einstein on this one - well, when it comes to work clothes. I don't want to have think about it. I also cycle to work so I do have change out of the lycra leggings etc. as I no longer wear a lab coat (which hides a multitude of sins.....).

However, my job entails unpacking deliveries and sudden adventures in DIY and bucket engineering. So my trousers are slightly stretchy and my tops are just smart t-shirts. But they're all the same style so i don't have to think, just stick it on.......
