The  “Real Housewives of New York City” -- Jill Zarin, Kelly Bensimon and LuAnn De Lesseps -- join environmental lifestyle expert Danny Seo, between 9 and 10:30 a.m., to kick off JC Penney’s denim jean drive (ends at 6 p.m.), at Manhattan Mall, 100 W. 33rd St. and Sixth Avenue.

Be one of the first 100 people to drop off a gently worn pair of jeans and get a $25 JCPenney gift card; the first 500 get a reusable tote bag. Donations go to Goodwill stores.
