Pas de deux? Ménage à trois? Forget it. Soixante Neuf is all the action you’ll ever need.

The jewelry designer’s newest collection of long necklaces in rose and yellow gold with gems will leave you even more hot and bothered than the record heat has.

Try the waist-skimming design with round links and flat, carved medallions, or the pink coral and rose gold piece. Delicate enough not to be overpowering but sure to get you noticed. (Anything to draw attention away from your sweat mustache.)

Throw them on and people will surely be wowed by your accessorizing prowess. Don’t be surprised if they praise your superior technique.

Mais oui, you’ll tell them.
