Black Strapless Jumpsuit This strapless black jumpsuit has been one of my best sellers for months now

Persol 3092SM Madeleine Swann (played by La Seydoux) wears Persol sunglasses in the trailer and promotional photos for SPECTRE and the music video for Sam Smith's "Writing's On The Wall"

While it's under $100, you'll look like a million bucks

The fitted silhouette features intricate lace detailing that creates a romantic, refined aesthetic while maintaining a sleek profile

Bonus: The dress is made with side pockets and a side slit, so you don't have to worry about carrying a purse and you'll be able to gracefully walk around at the celebration with ease

The trick to keeping sequins looking classy rather than costume-like is restraint everywhere else
