Can someone tell me the name of this bag?

Hi jeanhsiung! I don`t know if the bag has its own name, but I can assure you that I`ve seen it at least till the year you bought it in, so I gues, it`s not as "vintage" as in 10 or 20 years old...
 
jeanhsiung, I can't help you with this bag, but I hafta say that I LOVE the pooch in your avatar!!!!!

Sorry for the OT, hope more experts here will chime in soon.
 
BV doesn't give names to all their bags, so maybe this one is in that category. Vintage means different things to different people, I guess. To me, vintage would be at least 20 years old.

I've heard this called a circle bag, but that's not official, just descriptive.
