High heels don't accentuate your butt in a way that makes it appear larger or fatter. Heels actually enhance your butt's appearance by lifting your cheeks and accentuating your feminine curves. Heels also up the femininity quotient of many outfits and can even make the way you walk look more attractive.
Butt Lift
Heels make it look like your backside has had a literal lift. Heels cause your pelvis to tilt forward and your lower back to arch slightly.
As a result, your butt looks like it sits higher and might protrude a little more than before. Overall, this makes your butt appear more shapely and perky, but not bulkier.
Body Shape
Heels give your butt, legs, feet and even chest more shape by the way they re-align your body. The arch in your lower back pushes your chest forward, which improves your posture and makes you look curvier.
Your calf muscles contract and shorten, while your thighs tighten; this makes you look slim but toned. At the same time, heels add height, helping to give your body a long and lean appearance.
The higher the heel -- not including the high platform part -- the higher your butt appears to lift. Wearing heels also arches your feet, which has an attractive look and an elongating effect.
Hip Movement
A 2012 study done at the University of Portsmouth found that men consider women more attractive when they walk in heels rather than flat shoes. According to the study, women look more feminine in heels, as it makes them swing their hips and take shorter strides.
As a result, your butt and hips are emphasized when in heels, giving your overall appearance a womanly boost.
Clothing to Match Your Heels
To best feature your behind, choose a skirt that cups your butt, or have a tailor nip it in the center just below your tush. Make sure the skirt fits right; if it's too tight it will flatten your butt.
Stretchy bandage-style and pencil skirts are examples of skirts that look best with heels to show off your butt.
