Want To Look As Sweet As Kate?

There is a reason why social media users find Instagram so intoxicatingly addictive: The images produced therein have the type of hazy, beautiful, elegant quality which should be present in every moment, not just those which are uploaded via iPhone seconds before a glamorous event. Of the celebrities who use Instagram to document the most glittering moments of their perpetually thrilling lives, Kate Bosworth's snaps truly encapsulate a glitzy bohemian life in Hollywood, from milkmaid braids and rosy cheeks all the way to dainty ear cuffs and flowing floral ensembles. The actress and entrepreneur may just be this generation's indie icon.

For the launch of her new Style Thief App, which allows users to select favorite celebrity ensembles and "steal" the look, Bosworth Instagrammed her entire pre-party prep, from hair and makeup to the delicate floral Red Valentino dress she chose for her grand entrance. With a demure boatneck, elbow-length sleeves, a crisp bow at the waist, and a dreamy, pastel floral watercolor print, the dress was evocative of Dior's New Look, updated to fit 2014's latest painterly pattern trend. If you're inspired to try out a vintage-inspired ensemble for your next event, read on for the four pieces you'll need to capture Bosworth's brilliant Instagram look.

1. PAINTERLY FLORAL DRESS

Kate Bosworth's look achieves gentle flair while remaining cutting-edge thanks to its playful pattern and demure cut. ASOS's Wiggle Dress in Pastel Floral Print lends a similar look with its blooming floral motif and elbow-length sleeves.

2. LIP AND CHEEK STAIN

Get a healthy glow on lips and cheeks like Bosworth's with Benefit posietint; the pastel pink stain adds a natural flush wherever it is deposited.

3. LIGHTWEIGHT HAIRSPRAY

If you're looking to imitate Bosworth's intricate, braided updo, you'll need some well-placed pins and a sheer but professional-quality hairspray like Fekkai's Sheer Hold Hairspray to make sure your look lasts.

4. PASTEL SANDALS

Add vintage flair with a modern twist to your feet by wearing pastel pink sandals. Modcloth's One Suite Day Wedge in Bubblegum are delicate in appearance yet incredibly comfortable thanks to their wedge design.
