Four years ago, Andrew Blackmon got married. Like most grooms, he outfitted his groomsmen at a big, old-fashioned tux rental store. And like most customers at that store, he had a horrible experience. The traditional “for better or for worse” vow hasn’t changed much since medieval weddings. However, wedding fashions change dramatically every decade. Back in the ‘80s and ‘90s, men’s looks were baggy and boxy. Now? Not so much.
