From the looks of Dunham and Co.'s instagram posts, the wedding was a Midsummer Night's Dream theme (the occasion's hashtag was even #inthesewoods!).

Above, a group shot of the entire bridal party, of which, Dunham writes: "For those asking, our bridesmaid dresses were from @reformation and I found them charming, breathable and stylish. We can thank the beautiful bride, Isabel Bramlette Halley, for her good taste."
Here's an adorable photo of the 'maid's sweetly tied backs.
Dunham's dress in particular was floor-length, with a high Angelina-esque slit and cap-sleeves (you can find the style Dunham wore, called "Barrymore" here).
Close gal pal Audrey Gelman (whose even made a cameo in Girls!) posted a hilarious picture of Dunham and two other 'maids raising their bouquets to the sky and rocking sunglasses:

Dunham ended the steady stream of celebratory pictures with a glimpse at their bridesmaid gifts, crisp white pajamas with each bridesmaids' initials monogrammed onto the front pocket.
