If you tell people you’re going to Brimfield — the massive, thrice-yearly outdoor antique fair in central Massachusetts that famously lures the country’s best vintage pickers as well as interiors teams from stores like Ralph Lauren and J. Crew — you start getting loads of conflicting advice: what day to arrive, which of the 21 fields has the best merch, and even whether you should go for the ribs or the lobster roll (or something kind of amazing we discovered this time called the Pilgrim Sandwich. Seriously, get it.) But the one thing everyone agrees on? Don’t go in July.
