Generally, though, you can get away with sister sizes the larger you go, but as a child, you may be better off buying your daughter bras similar to your wife's size, so that she can grow into them. 32B might be loose, but she's a lanky kid that will put on some fat as she continues developing. So, pick up both sizes, or have the wife do the shopping, as is per norm of unwritten parenting rules. Mom takes care of daughter stuff, Dad pretends to talk about son stuff.
