Your mission, should you choose to accept it: Look toned and sexy without executing a single crunch.

Impossible? Nah.

Not when you fake it with Elaine Perlov’s take on the karate belt, which is just the thing to punch up your wardrobe and smooth out your lines. One wrap around the waist, and the sumptuous, two-inch-wide satin sash (which was inspired by her college studies in Japan) will complement your style and camouflage your trouble spots.

Drape it around oversize shirts, top off low-riding jeans, or sling it over a tee. When you’re done, just toss it in the laundry — it’s machine-washable.

Your new mission: Fight off potential borrowers.

And for that you may need an actual black belt.
