Was it a shoulder bag? Possibly the Vavin?

The other one that comes to mind is the luco or lucco, something like that.
Hmm..what about the Babylone?

As for the Vavin and Luco, I believe they were discontinued about 4 years ago?
Haha yeah I'm trying to remember all the totes and that's the only one I can think of with the sides the way you're describing them.
When did you see this tote or what made you think of it?
