Amanda Alagem's Instagram Story, above, vanished after a mere 24 hours, but the clip is forever ingrained in my mind. That's because it inspired me to buy her Jil Sander dress in the blink of an eye--and now I will wear it till the end of time. It's truly gorgeous--and hooray, on sale! The Harper's Bazaar editor also prompted me to pull out my Jenna Blake leather-strap heart necklace this morning, pictured below, and start contemplating Carolina Bucci's colorful beads and Marlo Laz's gold, diamond and sapphire necklaces for future days.
