'Heart of the City' after party

Beyonce was at the 40/40 club last night at Jay-Z's 'Heart of the City' tour after party. Mrs Carter (?) was looking very hood Chanel in a luxe jersey dress, long beads, gloves and monochrome shoes. I like the look, even though I'm a bit confused with the gloves (it's hot in London so I'm assuming it's boiling in NY)and I'm not sure about the flesh coloured tights.
