I should add that I have (contrary to the laundering instructions) washed kid's dress pants in the washer. He wore them often in high school for speech and debate and is a messy kid. But I would not trust him to do that himself.
Make sure they know to hang up suit and tie immediately after wearing and that they need to be dry cleaned.
Get easy-care/iron-free dress shirts and explain about removing it from drier after 10 min and hang immediately.
I bought something like this
