Gaga being Gaga, she went all out, accessorising with over 100 carats’ worth of diamonds in the form of the Tiffany Aurora necklace, which features over 300 brilliant diamonds, including a radiant 20-carat pear shaped diamond at the heart of the necklace.
She also dyed her hair blue to match the dress.
Opulence aside, there was a hidden meaning behind her choice of outfit. The dress was remarkably similar to the one Judy Garland wore in the 1954 version of A Star Is Born (did you know Gaga is the fourth to take on the role of Ally?).
Hers was designed by Jean Louis, and was a darker shade of blue, but with the same shape and puff sleeves. Although the singer hasn’t referenced the similarities, it hardly seems like a coincidence, don’t you think?
