This may be the worst goal to go after: Fit abs tend to bulge outward. The only way to have a stomach that collapses inward is to lose an unhealthy amount of weight through extreme dieting.
“Think about what's in your stomach: You've got your intestines, which often have food or air in them, and you may also be bloated if you're menstruating. While your belly can look flat, it's unlikely that it would look sunken in if you're eating normally,” de Mille says. Plus, eating too little will cause your nails to become brittle and your hair to fall out since you won’t be getting adequate levels of the nutrients your body needs for normal functioning, and your hormones will become imbalanced due to a lack of fat, Dr. Wright adds. Not worth it.
Dress to love your shape: Stripes, patterns, and seams that move on a diagonal as well as diagonals themselves are all super slimming, Raes says. Her other secret weapon: Spanx. “We see shapewear as this very uncomfortable, restrictive garment, but a light shapewear, like a tank or a bottom piece that rises up to the bra line, can make you feel contained and confident.”
