The New Instagram App the Fashion World's Already Obsessed With

Instagram's new app, Boomerang, is pretty much a fashion girl's dream come true. It allows you to upload your #OOTD or that amazing new It bag you just scored — but in motion. While your post isn't exactly a video, it plays a back-and-forth movement on a continuous loop. That means that when you're scrolling through your feed, you don't have to press "play" to watch Kendall Jenner and Cara Delevingne share kisses at the Balmain party — they're already smooching each other's cheeks.

Aside from satchels swinging and models hanging out, there are plenty of fashionable poses you can try. Read on for some ideas from our favorite brands and style stars to follow. Then learn all there is to know about the science behind Boomerang.
