Lady Gaga arrived at Barneys New York tonight in NYC for the grand opening of Gaga's Workship, and posted with CEO Mark Lee and Creative Director Dennis Freedman wearing a custom CHANEL gown by Karl Lagerfeld. Mother Monster actually took over the the world's most famous department store on Madison Avenue for the holidays and it all kicked off tonight! As you enter to shop Gaga memorbilla; including spiked gloves, flaming press-on nails, lollipops, tea cups, cookies, keychains, and more -- you'll be greeted with... more Gaga. There are artistic designs representing the 25-year-old entertainer all over the inside of the store and the outside. From sculptures, to lighting fixtures, and of course -- the store windows. It reminded me of something straight out of a Tim Burton movie meets Henry Selick's "James and the Giant Peach" when I saw it. Especially the giant spider replica of her and the inflatable claw. You'll have to go into the city to check it out this holiday season. Back to fashion.
