Tao Group is calling all bachelorettes to Vegas for the ultimate prenuptial party weekend. Taking place September 20-23, brides-to-be and their posses will enjoy a variety of earthly delights, including private performances by Chippendales dancers, Stripper 101 pole-dancing classes and what promises to be the World’s Largest Bachelorette Party (WLBP) at Tao nightclub.

Of course, the WLBP, which will attempt several world records, would not be complete without the perfect cocktail in hand. For the occasion, Tao Group Beverage Director Tim Keller presents the Skinny Girl Naked Cosmo ($14).

For this drink, Keller strips down the classic Cosmo that reached iconic status during the ’90s thanks to Sex and the City. Using Skinnygirl Bare Naked vodka, founded by former Real Housewife and real skinny girl Bethenny Frankel, the drink has half the usual calories. So sip away, bachelorettes. The dress will still fit.
