Lady Gaga wore a custom Ralph Lauren Collection for the opening night of her JAZZ & PIANO residency at the Park MGM in Las Vegas.

To perform with the legendary Tony Bennett, she wore a fully hand-embroidered evening dress made of over 53,000 Swarovski micro-crystals and over 250 rock crystals.

To close out the concert, she wore a black lamé tuxedo jumpsuit and white pique bib tuxedo shirt. The look also featured a detachable 240 meter tiered black iridescent silk organza and tulle skirt, finished with a sprinkling of over 7,500 Swarovski crystals and a belt beaded with over 2,300 black Swarovski crystals.
