"In love with my @reem_acra dress," she captioned a photo of herself in the princess-style dress. "Thank you @highheelprncess for everything! @rodortega4hair and @jennstreicher I love you all so much! @tessalynevents Thanku for making our dream day beautiful."
And for her final post of the evening, the former True Blood actress shared a full body snap of her gorgeous dress, which showed off her sweetheart neckline, delicate embroidery details and chiffon skirt.
"Sometimes you gotta get your dress fluffed!" she wrote.
Astin, 28, and Camp got engaged in January. They made their first appearance as a couple in June 2013.
Prior to their wedding, Camp revealed she can't wait to start a family.
"I'm really excited. I want to have kids," she said last month. "I'm ready to have a baby. I've worked a lot and I'm tired and I just want to stay and nest and be with Skylar and all that, which is something I'm really looking forward to."
