Let’s get right to the important stuff: the hot fashion tip from EXPO Chicago 2019, the big international modern and contemporary art fair underway this weekend at Navy Pier, is knee-highs.

Acquiring the Souliers piece would set you back a cool $22,000. But ten bucks will get you another Edelman offering, a big, bright, tissue paper blossom pulled from Borderlines, a wall of blooms mounted by CASE Art Fund, a nonprofit founded by Edelman and Anette Skuggeda last year. CASE supports and promotes fine art photographers who focus on humanitarian issues, and the money raised by bringing this wall down is going to another nonprofit, El Paso Matters.

21c is something new: a chain of hotels that include museum space collecting and showing only 21st century art. This next step on the lobby exhibit concept is coming to Chicago later this year at the former James Hotel at Ontario and Rush. No need to book a room: the museum will be open to the public, and admission will be free.  v

Through 9/22: Fri-Sat 11AM-7PM, Sun 11AM-6PM, Navy Pier, Festival Halls A&B, 600 E. Grand, EXPO Chicago, $30 ($45 for three days)
