I've got two things, "ecru" dungarees and a "parchment" denim pinafore, basically two versions of a creamy sort of white. I love them, they suit me, I'm going to wear them. But I have the fear. I keep telling myself to just accept the fact that they'll get marked. I don't have children, but I do travel by public transport and, you know, eat and drink. I used to have a coat this colour but didn't eat and drink in it. Any tips?
