My mother died recently and I am trying to sort out suitable clothes for my two sons (11 and 17) to wear to their granny's memorial service. (My mum opted for direct cremation so the memorial is just a small intimate close family thing). Both are wearing black suits and white shirts. Should my children both wear black ties, or, should they wear white ones? I have already bought a black tie for my eldest boy, however. Would it be strange for one to wear black and one white tie? Or should I just get them both to wear black tie? I Googled this which put a spanner in the works as Google says kids should wear white ties if it is close family. My mum was a stickler for things being done properly so I want to get it right.
