If you've ever wandered through a hotel only to find yourself in precarious situations with people wearing exactly the same dress as you, then you've lived the Lanvin for H&M video. In a new clip released this week, we get the first moving glimpse of the budget collection, which is sure to sell out in minutes. The pieces on offer: graphic tops, miniskirts, trenches, cocktail dresses, shoes, accessories and even lipstick. We have our eyes on a certain asymmetrical, voluminous black dress, but a similar number in mustard yellow is also on the list. We suggest planning early for your November 20 shopping trip (when Alber Elbaz's designs hit select H&M shops) and planning for long lines.
