This is going to be THE fashion event of the year. At 8 am ET on Saturday, November 20, fast fashion retailer H&M opens the doors to hoards of fashionistas who will snap up every single piece of the Lanvin for H&M collection. If you are lucky enough to live near one of H&M’s flagship stores (NYC, San Francisco) you can wait in line for your chance to grab no more than two of the same item. I’m bummed that I will not have that chance, to buy a couple pieces of Lanvin for the masses. I predict the stores will be cleaned out within hours. OK I could drive up to SF early tomorrow morning and stake out a place in line. But it’s cold, and it might rain, and I’d have to leave home about 5 or 6 am to get a good spot in line. Even then…
