Calvin Klein, fashion week

Fracisco Costa closed out fashion week on a high note with his standout Calvin Klein collection. The minimalist designer focused on sexy silhouettes and revealing fabrics for spring, which celebrated the female form—think bustiers, nipped waistlines, and curve-accentuating peplums.  Costa delivered a lineup of clothes that will look just as chic on the red carpet (those bustier dresses are the definition of understated elegance) as they will at the office (a perfectly-cut suit is always work-appropriate). See our favorites in the gallery!
