I was thinking that smart but casual. DH reckons I should wear a suit but I think that would be ridiculous as it's not that kind of environment and I need to be able to get down on the floor with the children (very young class).
I was thinking navy ankle grazer chinos
Simple T
Jersey blazer (not sure on colour)
Navy loafers
Maybe a scarf or something?
I would really appreciate your advice please.
