Lady Gaga pulled off another risqué look Monday night on her way to the Box nightclub in London with British milliner Phillip Treacy. Beneath a completely see-through fishnet dress, the pop singer flashed bejeweled pasties and waist-high black knickers.

The 29-year-old singer previously met Prince Harry during her benefit concert with crooner Tony Bennett. The singers are currently touring in support of their Grammy Award-winning album “Cheek to Cheek.” Their recent show at the Royal Albert Concert Hall reportedly raised more than $153,435 for the British charity WellChild, according to E! News

Gaga paired her dress with towering gold platform shoes with chunky scarlet red heels. Her blond tresses were fixed in place in a neat chignon and she accessorized with ornate silver earrings. She also wore matching fingerless fishnet gloves. ThePoker Face” hitmaker wore dark stick-on eyebrows and heavy glittery eyeliner and completed her makeup with pink lipstick. To add to the outrageous outfit, she wore a head-turning black hat designed by Treacy. Earlier in the evening she stopped by the designer’s Belgravia store. When she emerged from the store, Gaga was wearing the large feathered fascinator, much to the delight of waiting fans.

Gaga’s headpiece was so big that she had to be assisted by her companions to make sure she didn’t bump into anything, as the feathers obstructed her vision. Earlier in the evening, when she met Prince Harry, she wore a bell-sleeved sequinned ensemble with a plunging neckline.

Gaga said that whenever she is on a long car ride, she thinks about her former life, before achieving stardom. She said that with all the attention she receives now, she thinks of how to change the world, such as raising money for WellChild. "What will my music contribute to humanity?” she wrote on Instagram.
