You know the name — after all, not many people have an iconic Hermes bag named after them. Jane Birkin, whose style is celebrated in the book Jane & Serge: A Family Album, exemplifies a laid-back, chic aesthetic — an aesthetic thankfully captured in the 1978 photograph above. Let the English actress-singer serve as your star style inspiration and emulate her look with these three simple steps:
1. Start with relaxed separates: Choose patchwork jeans (Goldsign for J.Crew, $268; jcrew.com) with a slouchy cut for a casually undone vibe. Slip on a washed-out linen shirt (Loft, $45; loft.com) with rolled-up sleeves.
2. Accessorize with throwback extras: These delicate pieces have a fine-jewelry feel, like heirlooms left to you by a rich aunt (Melanie Auld cuff, $105; melanieauld.com. Moon and Lola necklace, $64; moonandlola.com). Add flat hippie sandals (Belle by Sigerson Morrison, $225; bellenyc.com) to emulate Birkin's boho cool.
3. Polish it off with a tinted balm: Keep your face bare, with just a hint of a matte berry hue (Revlon Colorburst Matte Balm in Sultry, $7; target.com) to enhance your pout.
