I have 9 at the moment. I really should get one more, to make it 10, hehe!
I've been buying Longchamp bags for around 6 years, I think, and I have all different sizes, as well as 2 leather Longchamp bags. I also have one vintage mint green crossbody Longchamp, which is pretty rare I think, that I absolutely love. But 6 of the bags are the classic Le Pliages - 2 of the smallest size, 3 of the medium size and 1 large.
