The singer wowed on Friday night at the Revel Resort & Casino in Atlantic City.
The 30-year-old took the stage in custom-made silver, cowgirl-inspired costumes by Ralph & Russo.
According to People magazine, a team of 20 couturiers worked to complete the outfits, to which they added more than 500,000 crystals from Swarovski Elements.
The singer performed some of her successful hits including “Single Ladies (Put a Ring on It),” “Run the World (Girls),” “Halo,” “Countdown” and “1+1.”
It was Beyoncé’s first performance since she gave birth to daughter Blue Ivy Carter in January.
In a “behind the scenes” video, which shows the preparation for her comeback performance at the Revel resort, the singer revealed that she was feeling nervous.
The concert is the first of four shows that the singer will hold this Memorial Day Weekend.
