Sienna Miller on a Double Date in Balenciaga Color Block Slingback Sandals

How lucky can one woman get?

Sienna Miller was seen out on a double date with two of the hottest men in Hollywood last Sunday, namely Jude Law and Robert Downey Jr. Of course, Sienna Miller was really there with Jude Law and RDJ was there with his wife Susan, but still, Sienna Miller technically had dinner with both Jude Law and RDJ that night. As if that wasn’t enough to be envious about, Sienna Miller did all of this in a very enviable designer outfit:

Sienna Miller is wearing an Azzedine Alaia dress similar to the dress Katie Holmes wore to the “Knight and Day” premiere in Spain. I prefer Sienna’s black dress with the dropped waist and the shorter flouncy skirt as it’s much more flattering than Katie Holmes’ Alaia dress.

On Sienna Miller’s feet are the Balenciaga Army Leather Color Block Slingback Sandals:

They retail for $825.00 but you can get them for $660.00 at Bluefly.com.

For lower-priced alternatives, these slingbacks in army green colors would do the trick:

But if you want to go even more army-inspired, try these sandals from Giuseppe Zanotti, Elizabeth and James, and 80%20:

I never thought I would use a pair of Giuseppe Zanotti shoes as a “lower-priced alternative” but since the ones here are over 50% off, they’ve become much cheaper than the 600-dollar Balenciagas!
