Girls star Allison Williams got married to Ricky Van Veen over the weekend - and wore a beautiful Oscar De La Renta dress. And after treating us to a gorgeous photo of her gown over the weekend, she shared another photo today of her look on the social-networking site.
"One more. This pretty much sums up my feelings about the whole weekend. Thank you all for the well-wishes, and thanks to everyone who made it possible" she wrote.

The intimate ceremony was held at a ranch in Wyoming and had a host of celebrity guests, including Allison's Girls co-stars, Lena Dunham, Zosia Mamet and Jemima Kirke, plus Diane von Furstenberg, Seth Meyers and Mindy Kaling.
Katy Perry and John Mayer were there too - and while some thought the pair had called it quits, they were apparently spotted 'holding hands' in the crowd.
"John and Katy looked happy," a source told People. "They held hands and sat next to each other during the wedding ceremony."
The pair reportedly split in February 2014, but Katy and John were spotted going for dinner with Allison and Ricky at the Chateau Marmont in January.
Neither have commented on the rumours, but John also reportedly serenaded the newlyweds during their wedding day, so there's a strong chance he was attending the wedding as a wedding singer rather than Katy's plus-one.
