This is one of two looks worn by Leslie Mann yesterday.

The blonde actress was one of many beauties to hit the red carpet at “The Change-Up” LA Premiere last night.

It’s feels like a very, very long while since we last saw Marchesa on the red carpet, but looking back Blake Lively wore one of their pieces just last month.

Leslie gave us our first look from the Marchesa Resort 2012 collection by wearing this sophisticated pencil dress.

At first I found the gold embellishments which help sculpt the shoulders a tad overwhelming (strangely) as they feel quite heavy, but on reflection I am more glad she;

a. picked a show stopper,
b. put her hair up and;
c. opted for complementary accessories.

Her hair was teased into a purposely messy high bun plus she carried the same Marchesa envelope gold clutch as the model in the look book picture.
