what happened to the nolita?

I don't think it was very popular. Just like the Plan B, I think most people who wanted a hobo opted for a Nikki instead. I remember seeing them at the sample sales and on Bluefly.
 
Here's a photo of the Nolita...

^^i had that same one! I thought it was a gorgeous hobo, very functional and not HUGE like the nikki. I was just too deep in the hole then and sold it.
 
It's a great bag. Perfect for someone who thinks the Nikki is too big and who maybe wants outside zipper pockets (which the Nolita has 2). I too think it wasn't that popular but it is a VERY nice bag and wonderful for someone who likes a decently longer strap drop.
