In the new book-to-film adaptation of The Great Gatsby, Daisy Buchanan wears this Tiffany & Co. sparkler, a piece that has all the drama and oppulence of F. Scott Fitzgerald’s heroine. We spotted the flapper style at a New York screening of Baz Luhrmann’s film and decided it would make for an even better accessory than a pair of 3D glasses! And you love it, too—so far the snap got over 10,000 likes. Keep up with gorgeous shots, like this Tiffany’s blockbuster, by following us on Instagram at @instylemagazine.

Instagram just got a big update, and we’re LOVING it. The photo-sharing app just launched Photos of You, a feature that allows you to tag shots of friends, places, and brands. Once added, the pictures feed into a new section of your profile, creating a scrapbook of your best Insta moments. We’ve already had fun tagging stars like The Bachelorette‘s Emily Maynard (@emilygmaynard), who stopped by our L.A. office to show off her new jewelry collection for Towne & Reese. Got a photo of InStyle that you want us to see? Tag us @instylemagazine. We’ll be looking!

In honor of Mother’s Day, we’re dedicating this week’s #ThrowbackThursday on InStyle’s Instagram to Christie Brinkley‘s July 1996 cover featuring her daughter Alexa Ray and son Jack, who were 10-years-old and 11-months-old at the time, respectively. “We’ve managed to find happiness and to feel whole in our unit of three,” Brinkley told us for the cover story. “Our little family is filled with so much love, I think we came out as well as anybody can.” Happy Mother’s Day!
