"I never thought I could wear that!"

A big fan of shift dresses, GE marketing exec Jessica Beegle knew they highlighted her shapely legs, but didn’t realize they also concealed another asset: her slim middle. "I never thought to play up my waist—it just goes straight up and down." With a few key pieces, we gave Jessica some extra curve—and made her look killer from head to toe.

"I learned it’s actually more flattering to tuck your shirt in tight!"

"I gave up on jeans a long time ago," says Amanda Idoko, an aspiring actress and legal assistant. "I have to buy them in one size to fit my thighs, but then they’re too big in the waist." Determined to restore her faith, we found her the perfect pair: Spun out of stretchy, comfortable denim and generously cut in the thigh, they hugged Amanda’s every curve. "When I tried them on, I knew they were different."

"These fit great, were really comfortable and didn’t have that weird bunching problem."

"I cover up in baggy tunics and dresses—nothing too clingy," says Katie Hards, who is getting a master’s in food studies. But her drapey looks were completely masking her sireny curves. The fix: a pencil skirt and chambray top—crisp-yet-relaxed pieces that show off her frame but aren’t too restraining. "I love this outfit! It makes me feel like I have a really sexy shape—not self-conscious."

"I used to hide in big, blousy tops and loose A-line skirts."
