When Eva Longoria wants a wow-worthy moment on the red carpet, she knows who she can turn to—friends Georgina Chapman and Keren Craig of Marchesa. “Georgina calls me and will say, ‘I have the perfect dress for you,’ and I’m like, ‘Perfect!’” the actress told InStyle.com at the Lay’s “Do Us a Flavor” campaign launch in New York. Recently, she was grateful for the blush tulle gown they lent her for the Cannes Film Festival last month. “The color makes me feel so beautiful,” she told us. “And that dramatic train! I feel like a princess. It’s funny because I’m such a small person, sometimes I can be overwhelmed by a dress, and I just think Marchesa just does it really well-proportioned.” We can only imagine how sweet life must be with Marchesa on speed-dial!
