ooh, which ones do you use the most often??? i'm curious!I know many women whom have "only" one Birkin bag and they're completely happy about it! For most of my friends it's just "a bag" and once they've had one they're happy to use it for years to come.. I would say that it's more unusual to have several Birkins that to have just one or two. I have a few too many and I still end up using the same ones again and again..
So yes, I think that you can be very happy owning one Birkin bag.
Your signature is the reason I got the orange. I love it! Thank you so much, I love that pop of color. I don't like Blue Jean but I have Blue de prusse.
