Easy off: When it's hot and sticky, zippered ankles are a godsend for getting off tight jeans.

Curvaceous! Flattering doesn't equal tight; it means roomy enough for real curves.

Tip: How skinny jeans adapt for summer: They're newly cropped above the ankle to show off sexy sandals.

Bright colors

"Bright jeans make a splash in a sea of dark-blue denim." -Joie Rucker, Designer and Co-Owner, Rich & Skinny.
