Making for one of the sexiest parties of the weekend, CR Fashion Book Magazine held its launch party during Mercedes Benz Fashion Week in New York City on Saturday night (September 8).

The newest publication to hit the fashion industry boasted some of the most gorgeous women at it’s premiere party, as the lineup of ladies included Bar Refaeli, Kate Upton and Karlie Kloss, to name a few.

Before arriving in her cleavage baring black dress, Miss Upton took to her Twitter page to share some exciting news about the mag, writing, “So excited to be on the cover of CR Fashion Book by Bruce Weber @Carine_Roitfeld !!”

Also in tow for the evening was the creator of the fashion book, former French Vogue editor Carine Roitfeld, who showed up to the event in a sexy high slit black dress.

Details of the magazine were recently released to Women’s Wear Daily, which announced that the publication is to be released biannually while the premiere installment will hit newsstands later this month.
