Those silhouettes...

Celebrities and those perfect hour glass figures... They all seem to have smooth curves with no lumps, muffin tops, tummy rolls and bumps. 
Their secret?

Shapewear!

All of them, Kim Kardashian, Jennifer Lopez, Lindsay Lohan, Adele, Beyonce, Kristen Stewart, Tyra Banks... They wear shapewear underneath their dresses to give them that silhouette- The flat stomach and smooth curves.
