Lopez, shown here in her design studio, has put her fashion stamp on each piece in the line. Thanks to her insistence on comfort and fit, everything—including this cardigan and the signature skinny jeans—has built-in stretch. Thanks to her love of knitwear, even platform boots get a cozy ribbed cuff.
