Your flats-plus-jeans combo can go in a couple of directions. The first is the long, lean look of slender-fitting jeans that highlight the simple elegance of flats. Another option -- rolled-up jeans with flats -- creates a cute, relaxed look. Mix up your selection of flats with both neutral and bold tones to best accessorize both blue jeans and brightly colored denim.

Skinny and Tapered Jeans

Skinny jeans, jeggings and tapered slim-cut jeans pair beautifully with flats. To pull off a gracefully sleek look, your jeans' lower calves and ankles should be slim-fitting or tapered. Pair brightly-colored jeans or jeggings with neutral-toned flats or try colorful flats with black or blue jeans. On top, wear a flowing shirt that falls at or below your hips.

Cuffed and Cute

Cuff your boyfriend jeans or non-tapered slim-cut jeans and pair with flats. The cuffed look showcases your shoes, so this is a great time to break out your cutest flats. To pull if off, make sure your cuffs look intentional instead of like a quick fix for jeans in need of tailoring, and reserve the look for casual occasions.
