Here's Lady Gaga, arriving at her father's restaurant, Joanne Trattoria, in NYC, carrying a vintage Hermes Kelly Bag that has been...well loved. Gaga has a history of carrying altered, or, depending on your perspective, "defaced," Hermes bags, so it's not a stretch to think that she likes the half-destroyed look of this one. You can find pre-owned Hermes Kelly bags in far superior condition for sale on Portero.
We've seen Gaga with a similar Hermes Kelly Bag before, so it's possible that she and this Kelly have simply been through a lot together, and she feels compelled to continue carrying it for purely sentimental reasons. Or maybe a busted Hermes bag is just a key component of her unique vision for this particular fashion ensemble. You can see all of her ladyship's favorite Hermes bags (and wonderfully bizarre outfits) in "The Many Bags of Lady Gaga."
