She was the guest of honour and Julianne Hough certainly dressed to impress in New York on Tuesday night The Safe Haven actress teamed up with QVC for the 20th annual FFANY Shoes on Sale benefit and went all out for the occasion in a revealing backless dress.The gala was held at the Waldorf Astoria in New York to raise money for breast cancer research, education and awareness with a dress code of cocktail attire and fabulous pink shoes. While Julianne looked fabulous in her shimmering navy dress, it was impossible to tell if she adhered to the shoe code as her outfit was floor length She wisely arranged her blonde hair in an updo so as not to distract from the main feature of the dress, the open back. After being announced as the 2013 spokesperson for the event earlier this year, Julianne said: There are many bonds that women share. Unfortunately breast cancer is one that negatively impacts so many Having the opportunity to take a positive bond like a passion for shoes and adapt it to benefit a worthy cause such as this is incredibly fulfilling.
