Attending a private dinner for Elie Saab in New York City on April 5th, Emily Blunt smartly stayed devoted to the designer in a fifties-inspired dress out of his Spring collection and grey lamé evening clutch. But she broke away with a pair of Spring 2012 Sergio Rossi peep-toe sandals with enough subtle sparkle to draw all eyes down to the floor.

The exquisite detailing turns them into a crystalline dream, and the pitch-perfect piping matches the frock almost too well! But overt matching is in this spring – and so is the more refined heel. It’s refreshing to see a starlet out in a more delicate silhouette for a cocktail look. (As in, not a chunky peep-toe pump!) Emily only reinstates the fact that there’s a new shape in the air this summer.

Recreate Emily’s sun-drenched look with Preen’s Flame dress (on Net-a-Porter for $1,440), a similarly square-necked stretch-crepe number that fits and flares in all the right places. Then why not trade sparkle for earthiness? The laser-cut Chloris sandal by Sergio Rossi (at Barneys New York for $835) will dress down a feminine look and they still keep the mood light and girlish.
