Everything about this Instagram pic of London-based stylist Caroline Sieber, above, is glamorous, from the Positano backdrop to her white scalloped bikini. Her choice of a floppy wide-brimmed hat is also suitably fabulous--and it's all I want right this very minute. To completely shield my face from the (already-had-too-much) sun. To add more dramatic flair to my swimsuits. So far, I like these options from Melissa Odabash, Bop Basics, and Jonathan Adler.
