Hey kids, fun fact: Did you know that you can make a dress out of the same material used for fishing waders, iPod cases and saddle pads? Of course you did, you overachieving fashionistas, you.
The material is neoprene, and it's so popular that two—two!—top actresses are suiting up in it. Maybe the ladies are going to premieres. Maybe they're diving for pearls. Does it matter, when Rachel Weisz and Charlize Theron both look so hot?
We can't decide which actress wore her Lanvin sheath better.
Rachel slipped into a green version of the dress just last week for a visit to Good Morning America. She's promoting The Bourne Legacy, which may or may not involve pearl diving, but we certainly dig her nude Gianvito Rossi peep-toe heels regardless.
But even before her there was our fave South African beauty who wore the dress in black back in May, before anyone knew that Prometheus was a hideous waste of time. She paired the frock with flippers—oh, wait, make that Christian Louboutin Decoupata ankle booties.
Now it's your turn. You tell us: Which deep-sea-diving hottie wore her Lanvin best?
