7 1/2" Flared Jeans
You can pull off '70s-style jeans if you remember a few simple rules: Generally, the taller you are, the wider a flare you can wear. But the higher the waist of the jeans, the longer your legs look, so even petite gals can get in on the trend. Avoid voluminous tops, and keep the rest of your look modern. And make sure the hem hits the back of your heel, with just the front of your shoe exposed; pointy toes are more stylish than rounded ones. Here are our picks, from boot cut to bell bottom.
