(As if we needed to salivate any more!)
In the picture, four models appear in a shadowy room donning completely black looks, all of which are reminiscent of garments seen in Lanvin designer Alber Elbaz's recent high-end runway shows.
Starting from the left, there's a single-sleeve minidress with a voluminous flounce at the shoulder, worn with a thick black belt.
Next, there's an older gray-haired model sporting a belted and textured jacket with a dramatic collar, while a younger brunette woman wears a long tuxedo jacket over a mixed-fabric skirt with an asymmetrical hem.
The last look, on the far right, is what appears to be a sleeveless party dress covered in bows, worn by Natasha Poly.
The four women are also accessorized with thick black sunglasses, white pearl necklaces, and chunky bracelets featuring pops of bright green.
"H&M approached us to collaborate and see if we could translate the dream we created at Lanvin to a wider audience, not just a dress for less," Elbaz said in a statement last month.
"I have said in the past that I would never do a mass-market collection, but what intrigued me was the idea of H&M going luxury rather than Lanvin going public."
It certainly looks like they were successful in upping the luxury factor.
Be on the lookout for a second image H&M is promising to leak later this week.
