Blazer over jeans
The clean lines of a blazer's lapel immediately hides curves from your back and upper arms. Pair a longer-cut blazer with straight leg jeans for a slimming effect on your upper torso while also hiding your bottom. An open jacket with a V-neck top underneath will draw attention to all the right places.
When you pair nude pumps or sandals with bare legs, the effect is an immediate lengthening of the legs, making you look taller and thinner. Nude pumps have been the red carpet secret of celebrities for the past few years. For dressier occasions, pick a patent leather nude pump with a platform for added height and shine. Be sure to pick the right nude for your skin tone!
Tan is golden
A faux-tan can help minimize the sight of blemishes from cellulite, stretch marks etc. With a clean visual line on arms and legs, the body naturally looks thinner. If you prefer to skip the fake bake, go ahead and invest in a bronzer or illuminating lotion/powder that'll give your skin a healthy glow.
Black on black
When wearing black tights, leggings, or skinny pants, pair the legs with a pair of black pumps or sandals. The same principle behind nude pumps and bare legs applies here -- when you create a monochromatic line, the body is immediately lengthened.
