StyleWeek Northeast returns to Providence on Sunday with a batch of emerging and fledgling fashion designers ready to show off the season’s newest styles. Throughout the weeklong event, designers will debut their collections on the runway during shows described as fashion-forward and thought provoking. Each night will begin with a cocktail hour and an accessory showcase before spectators take their seats in front of the catwalk. Following Sunday’s runway shows, an opening party will be held at Vanity Restaurant and Lounge.
