Kate Moss recently collaborated with a British sculptor to create a Champagne glass modeled after her left breast.

This is nothing new. The original “coupe” was said to be modeled after Marie Antoinette’s left breast (although some think it was after Madame Pompadour’s). 34 restaurant in London, where Kate had her 40th birthday lunch in January, commissioned Lucien Freud’s daughter to craft the glass mold. They describe the coupe as an “intricate abstract design reminiscent of Art Deco symmetry which,when held at an angle, shows a beautiful curvy shape.”

Kate, whose signature is on the base of the glass, also made a grapefriendy statement: “Champagne is always associated with celebration and happy occasions and I had fun creating this beautiful coupe.” The glasses aren’t available to buy; you’ll only be able to drink from them at the London restaurants The Ivy, Daphne’s, Scott’s and The Club at The Ivy starting in October.

Despite the coupe’s sexy lineage and how pretty it is, Champagne houses actually don’t recommend drinking Champagne from them. The large surface area can make the bubbles dissipate faster, and of course if you’re getting tipsy there’s just a lot more chance you’re gonna spill.

So, we’re all supposed to drink out of a flute, right? Wrong. The winemakers and Champagne reps I’ve spoken to say to just drink out of a white wine glass. Champagne is wine after all, it just keeps the carbonated bubbles that occur during fermentation in the wine bottle rather than letting them release into the air. A regular wine glass also provides the best way to get a full sniff of the aromas.

That said, flutes and coupes are just so pretty and what people usually serve Champs in. And Kate’s coupe looks like it’ll actually give you a perfect serving of Dom. If it was modeled after Kate Upton’s, you’d be wasted.
