Popsugar Fashion Celebrity Fashion Sienna Miller Zigzag Bikini in Italy 2018 Sienna Miller's Bikini Is So Devilishly Sexy, It Plays Psychedelic Tricks on Your Eyes 25 July 2018 by Sarah Wasilak First Published: 24 July 2018 Image Source: Backgrid As POPSUGAR editors, we independently select and write about stuff we love and think you'll like too.

Sienna Miller is just the latest of the celebrity pack to land in Portofino for holiday. The star lounged on a boat with a group of friends, showing off her crochet bikini (which we're pretty certain is from the Italian brand Missoni) from every angle as she jumped in a kayak and sunbathed on the deck. Sienna's look was complete with a pair of dark Ray-Ban sunglasses and some gold jewellery, but she need not accessorise further since her swimsuit did all the talking. While her design appeared to be purple from the front, it was sea green from behind, which, in our opinion, makes this even better than a reversible design. Read on to see some close-ups of the adorable two-piece, then shop similar colourful options that will, at the very least, make them all look twice.
