I don't know why this is gnawing at me, but hopefully you guys can help . I was in a long line at the post office and the lady in front of me had an LV shoulder bag (mono)...it looked like a Piano or Mezzo but without the vachetta on the bottom. It had a zip top and that beige-y canvas lining (zipper was open). No outside pockets or hardware. I have been combing vuitton.com and I first thought it might be a Vavin but those are open-topped, correct? It definitely was NOT a sac plat. Is there a discontinued style that is a square-shaped, zip top mono with no vachetta on the bottom? Any ideas? Wish I could have been sneaky with my phone camera but no such luck. TIA!
