And for Emma Chamberlain at the Met Gala 2025, that meant a floor-length pinstripe dress from French fashion house Courrèges. It looked like a suit vest from the front, with lapels and a pocket square, and the skirt of the custom-made dress ended in a long train. Sounds classic at first, until we saw the back of the dress.

Emma Chamberlain put a nearly naked twist on the 2025 Met Gala theme "Superfine: Tailoring Black Style." While stepping out at The Carlyle ahead of the Met Gala, the creator showed off a backless suit dress that featured a thigh-high slit and a side boob-baring design.
