Croptops and hiphuggers are ruling the runways, so it's time to bone up on tummy etiquette. Please consider others when adopting this year's styles.

A GIANT SUCKING SOUND Please take that tired old navel ring OUT! Even worn-out Naomi Campbell has said goodbye to this suburban girl look. It reminds us of nothing so much as a bathtub drain. Pull the plug.

The same thing goes for belly necklaces, chains, and the like. A tasteful tattoo is permissible, but it means committing to a flat stomach forever.

HIPHUGGER NO-NOS The no-hipped Idalis look is hot now, and many victims think that this is a good body type for the low slung look. Oh no, no, no. Honey, they are called hiphuggers for a reason. You gotta have hips. The thing is, you have to have hips AND a flat belly, whether via sweat, genetics, or a discreet plastic surgeon.
