John Bartlett may have just released his first collection with Claiborne, but he’s already launching it beyond the throngs of Macy’s. Starting June 18, the line will have its own stand-alone store at 143 Seventh Avenue South. The shop will be stocked with shorts for $55, polos for $39.50, and sport coats for $89.50 for four days only. Now, this is the joy of proper pop-up planning — with Father’s Day that weekend, it might be worth the trip. 6/186/22. 143 Seventh Ave. S., at Charles St.; daily (117).
