I need a spot of help. We've been invited to a wedding but I really don't k is what to wear. I am wearing a simple knee length pale blue dress. I was thinking of pairing it with pearls and nude shoes but wtf do Ido about a hat? Do people even wear hats these days or is it all facivstors? Does it have to be blue? Would it look odd if I went for a pastel yellow or something? Dress attached
