The super sheath

While I am in no hurry for fall to arrive, I must admit that the clothes are looking spectacular.  Of particular interest to me are all of the sheath silhouettes -- I'm a sucker for a simple, knee-length sheath dress.  The fitted silhouette is polished for work, and cool enough to go out afterwards.  (No wonder Kate Middleton wears them so often.)  A few of my fall favorites:

Diane von Furstenberg Paltrow Dress, $375.

Zara Racerback Dress, $79.90

J. Crew Emmaleigh dress in Super 120s, $188 (available in both tall and petite).

French Connection Fast Carlotta Sateen Dress, $188.

Rachel Roy Bow Dress, $398 (this is so Joan Holloway to me, in the best way).

Nanette Lepore Waterfall Dress, $252.

What's your go-to silhouette? 

(PS: my favorite J. Crew sheath dress is now available in tall!)
