Lively wears Earnest Sewn's LC fit in the dark Olivia wash, which the designer, Scott Morrison, says, "slims the silhouette" while the tapered cut "complements Blake's long, slender legs." Try leaving the extra-long inseams as is—wearing this style with heels adds even more length to the body. "The LC works well on a straight boyish figure because the fitted stretch denim hugs and defines the body creating the appearance of sexy curves," adds Morrison. Other fans of Earnest Sewn include Sienna Miller, Gwyneth Paltrow, Heidi Klum and Kirsten Dunst.
