Essential Blue Blazer

Hi. My son is at the age where I want to ditch his discount blue blazer that has generally lived the life of a college kid and get him a classic, high-quality blue blazer that will be worth keeping in his wardrobe for many years. In the past I would have gone to a certain store that i will not mention here but i think their quality has dropped much while their prices definitely have not. Does anyone have a suggestion for a store that i can check out for this type of item? Thanks for any thoughts.
