White Linen Night is Aug. 3 in New Orleans

Zoom in: The festivities officially focus on art galleries between the 300 and 600 blocks of Julia Street, with live music, food trucks and drink vendors scattered throughout the surrounding streets.

• But others will throw their doors open too, often with bottles of wine, DJs or other attempts to entice the crowds to peruse what's on view.
• The Ogden Museum of Art also has a new exhibition opening that night.

What's next: Stop by the Ogden for the official afterparty, too.
