any white suit looks cheap. and steals focus from the bride. the bride should be the only one in white. the men can rent black blue or gray suits from any tux shop. if you buy them online, they won't arrive in time for the men to have them altered, and they will look too baggy or too small. your wedding photos will last a lifetime, so send the guys to a shop where a tailor can take their measurements and do the suits right.
