'Ring bearers and train bearers are most often dressed in white suits,
preferably with short pants.'
'Tiny boys and Girls wear slippers with a strap and white socks. If
they are dressed in white, their slippers are white, but if they wear

black patent leather or a contrasting color--more often the latter.'
