Waste not, want not: Behind the Seams talks about what happens to what’s left behind on the cutting-room floor.

• Hollywood-based Reel Green Media explored costume-design waste through its first Sustainable Sirens project.
• Minneapolis designer Angie Arner is helping brides everywhere keep their promises that you’ll wear that bridesmaid dress again (although it may look nothing like it did in those wedding-party portraits after Arner gets through with it).
• Vogue editor Anna Wintour has shared her surprising rule for maintaining a well-edited closet: “How many handbags? How many shoes? How much of a thing does everyone really need?”
• If you’ve ever ordered from eco-boutique Tobi.com, you may have been surprised to receive your merchandise in a reused box bearing the name of another company. What an innovative concept!
