My almost 3-year-old still wears a bib. In fact, he generally insists on it. I've trained him well. :) I had a hard and fast rule (as much for DH as for DS) that DS had to wear a bib whenever he dipped. DH seems to always serve him ketchup and that's a stain that's hard to get out sometimes. Anyway, now DS will ask for a bib if there's ketchup involved. :) I plan on keeping him wearing a bib until he won't.
