Luann de Lesseps Reveals Details on Her Three Wedding Dresses

Luann de Lesseps bid 2016 a fond farewell in a stunning wedding gown designed by Randi Rahm. On Saturday (December 31), The Real Housewives of New York City mom married Thomas D'Agostino in Palm Beach, and she simply slayed the nuptials in her elegant dress, which she accessorized with silver pumps and an understated bouquet. It was one of three dresses the NYC-based designer designed for the newlywed, as she previously told The Daily Dish.

Later on she was spotted in a sexy sequined gown.

And she kept the fashion dial turned all the way up on Sunday during the couple's post-wedding brunch in a LWD (little white dress, natch) with a plunging neckline.
