That's too bad. If you don't carry very much you might like the small instead of the medium. But it really is a soft, lightweight, puddly bag. Maybe look at at some of the other lines? I find Longchamp leather bags tend to be lightweight in general which is a big deal for me. I have a few quadris and they are lightweight, still soft but have more structure, and an adjustable strap.
Thanks for your help; I did obsess over "small or medium???" for the longest time. I prefer to carry a larger looking bag, even though I don't carry a lot of stuff in it. I decided that the way the bag slouches will make a small appear even smaller, if that makes sense.

I will take a look at the quadris; thanks for the recommendation. One major factor that drew me to the Cuir is that I love the casual vibe of the purse.
Have a great weekend!
