So what makes this particular pairing so appealing? Well, it’s one of the best outfits to create the illusion of an hourglass figure--but also hide any insecurities. The tucked-in top and full skirt both narrow in at the smallest part of your waist, and then the long vest skims over your hips and thighs to create a streamlined effect. Pair it with nude heels or wedges for extra slimming benefits.
