Who better to seek wedding inspiration from than our favorite Girls squad: Hannah, Shoshannah, Marnie, and Jessa. Lena Dunham just showed us a sneak peek [1] from the HBO show in the form of a behind-the-scenes shot — and it's from Marnie's forthcoming nuptials! While actress Allison Williams recently got married in a feminine Oscar de la Renta gown [2], her second ceremony of the year took a decidedly bohemian route.

Marnie chose an embellished bell-sleeved design finished with lace and completed her elegant look with a floral crown. Meanwhile, she dressed her bridesmaids in lavender wear-any-way numbers [3] you'll want to snag for your own girlfriends [4], too.

Read on to see the new trailer for Girls season five [5] — which begins on Feb. 21 — and watch Marnie and Hannah prepare to walk down the aisle, then shop for similar bridal designs inspired by the four best friends.
