Is this the look you're going for? There are seven pictures, it's the bottom left.
Although that's Emanuelle in the pix, la Corine wears leather trousers. Methinks absolutely no to leather + leopard print heels. Leather might look a little try-to-hard, unless dressed with a twist. Either dress it down, or with something that speaks a different fashion argot, iyswim, though the tux might do that for you.
I have to admit, that bottom left picture is my default "going out" outfit. And since I am not uber-stylish, it is probably past its best. But I am heartened to see the lovely Vogue ed. still rocking the look. And good for her!
Haven't been to LTG, so can't be absolutely spot on.
