For the ceremony, Wirkus wore a gorgeous gown by Pronovias. And for her intimate reception, she changed into a white patterned jumpsuit by Nadine Merabi, which she accessorized with a custom "Mrs. Raih" bag designed by Island to East Side.

The reception, which was planned and designed by Erica Marie Events, was held at the private home of Chris and Jean Raih, who are the groom's brother and sister-in-law.

The couple and their loved ones enjoyed a candlelight dinner, catered by Food First Events & Catering and drinks by Authentic Cocktails, and decorated with floral arrangements by Lauren Ghani.
