Oh Mon Dieu! For H&M's latest collaboration the high-street outpost has gone Rive Gauche and joined forces with the famed Parisian couturier, Lanvin. Designed by artistic director Alber Elbaz, the women's collection is filled with signature one-shoulder ruffle dresses, kitschy vibrant accessories, and covetable coats, including a black trench with glass buttons that is just divine. We have a feeling the full tulle dress"in mocha or candy apple red"will be this year's Rodarte for Target party frock, sashaying its way through the blogosphere at lightening speed. And while the cocktail dresses, bow-bedecked gloves, and strands of chain-meets-pearls won't be available in-store until November 23rd, you can catch a glimpse of the entire masterpiece in this special video preview below!
