Lady Gaga’s holiday workshop finally opened inside Barneys at midnight last night.  To celebrate, she wore a custom made Chanel gown that wouldn’t look inappropriate walking down a royal aisle.  The white tweed dress resembled a jacket on top before exploding into a full skirt.  It was accessorized with pearl, bows and camelias—just in case it wasn’t quite clear it came from the house of Chanel.  The look was quite conservative for Gaga and very fitting for the evening’s festivities.  Click through for a closer look, as well as Lagerfeld’s sketch of the gown.
