It’s not for me, as the patterned squares are quite large and the coat looks long, so it would swamp me.
If you like it, though, and can carry such a bold coat, then go for it. It certainly looks cheerful and definitely a change from the usual black, grey and dark browns.
I thought this looked lovely for a Spring coat but my very conservative son told me not to be ridiculous. I'm still tempted. Would you wear something so loud?
