Who: Lady Gaga.
When: Wednesday, August 3.
Where: Tony Bennett's birthday party in New York, New York.
What: A custom strapless black velvet gown by Brandon Maxwell.
Why: First the First Lady for a state dinner, now Lady Gaga: Brandon Maxwell is having a great week. He's been styling Gaga since Nicola Formichetti passed him the baton in 2013, and he has helped usher in her Tony Bennett-collaborating, old Hollywood-inflected look (designing it along the way). In black velvet, an asymmetrical strapless neckline, and with a thigh-high slit, the look is glamorous and elegant — the perfect gown for Bennett's 90th birthday celebration, where Lady Gaga performed Wednesday night.
