I normally don't like black on children, but this (and Halloween) might be an exception. I would use black and white gingham piping or binding, or black rick rack. I have also seen cute black/white check or stripe ribbon that would work. I think these yellows fight each other. Just my 2 cents. Jan M.
Those are just adorable. I do so love the smocked bee I am so happy you added the pictures, I think black is the way to go. I like Jan's idea and your picture of black and white ribbon. Here is just plain black, but think I will find some black and white.
I like the black. Maybe it is because we are in the North but we do put black on little kids. Many Christmas dresses are black - black velvet, black taffeta, dressy fabrics but I think we might see as many black as other colors. Maybe not as often on really little babies but kids around here wear black all the time.
