We're having the ring bearer wear a tux that is age appropriate. It costs about $70, everything included. Your tux shop should have these or be able to order them. Edited to add: A friend several years ago had a ring bearer in her wedding and dressed him in a shirt and tie instead of a tux.
The engagement ring cost about 3.3k.....but she wants a simple wedding ring for everyday wear (hiking, camping, gardening, etc.)....so we are going with simple, engraved, tungsten bands...less than 1k.
