Catherine, Duchess of Cambridge, stepped out this week in a number of gorgeous, effortless sexy ensembles.

The royal and mother of two, 34, totally stunned in a gorgeous, light pink Alexander McQueen dress that left a truly feminine impression. A daring, low-cut neckline was offset by the outfit's flirty, demure skirt, while a stiff peplum added some structure to the frock's soft lines. (Similar here, here and here.)

Middleton did it again in one of her favorite dresses she's rocked before in 2011 and 2012: A pale blue Roksanda knee-length dress with asymmetrical sleeves. (Similar looks here and here.) Her go-to L.K. Bennett pumps, and L.K. Bennett Nina box clutch gave the recycled look a fresh springtime flair.

The Duchess wasn't the only one to rock killer styles this week. Actress Rachel McAdams, 37, also turned heads in an effortless red midi dress with alternating sheer and velvet panels. The swingy silhouette with a schoolgirl-esque collar put a classy spin on the skin-exposing sheer trend. (Similar look here and here.)
