Luann D'Agostino Spills The Secret "Something Blue" From Her Wedding Day

Luann D'Agostino had a pre-tty big New Year's Eve. Sure, she rang in 2017 with plenty of champagne. But, it was also Luann's wedding day—and her husband Tom's 50th birthday! So, when it came to choosing a dress, "Lu" wanted something worthy of a major celebration.

The Real Housewives of New York pal turned to her friend, the designer Randi Rahm, to sticth up something elegant and lacy—or, as Luann put it, "traditional and sexy." Naturally, the dress and the bride were both completely gorgeous.

But, there was more to Luann's look than body-skimming lace. The etiquette expert recently sat down with The Lookbook to reveal her something borrowed, something blue, something old, and something new. As it turns out, a borrowed blue garter checked all the boxes for old, borrowed, and blue. The something new was a real gem: a diamond necklace that Tom bought his bride for Christmas.

Clearly, Luann was the best dressed woman in the room. But when we asked which other 'Wife really brought it style-wise, Luann named Dorrinda Medley—but only because the bride herself helped select the outfit. "Dorrinda was my bridesmaid," Luann said, smiling. But, as long as you don't show up to someone else's wedding wearing white, anything you want to wear is fine in Luann's book.
