Wolves in Chic Clothing by Carrie Karasyov and Jill Kargman
You may know Jill Kargman from her hilarious Bravo show Odd Mom Out, but before she did that, she was writing chick lit, sometimes on her own, sometimes with her friend Carrie Karasyov. Wolves in Chic Clothing is the story of Julia, who catches the eye of Lell Pelham, the heiress to the Pelham's jewelry store fortune (think Tiffany & Co.). When she and her friends take Julia under their collective wing to remake her image, they think it's all in good fun. Soon, Julia's turning heads everywhere, but what happens when it's Lell's husband who's interested?
