That fitted top you loved five years ago might not hit the same way anymore. Your body has shifted, and the midsection is usually the first place you notice it. The good news? You don't need shapewear or a bigger size. You need a smarter silhouette. Peplum blouses are known for visually slimming the midsection, which is a big reason why they're back in style! These clever tops work by cinching at the narrowest part of your torso, then flaring out to cover the tummy area beneath. The effect is instant: A defined waist and a smooth line through the hips.
