ok, here is my 2 cents.
I just returned my small black gathered Sophia because, since I always carry my bags on my shoulder, it kept bending real weird in the middle and poking my side! Drove me batty! Also, the small was TOO small and I don't have very much in my purse to begin with, so no Sophias for me even though I know they are the popular favorite right now. They just don't work for me.
So, I traded in my Sophia gathered for the Kristin marcasite pleated satchel.. This bag is gorgeous and I love the way it looks. It is not too heavy on my shoulder and there is plenty of room inside. That being said, my only complaint is when you sit her down to unzip her, the bag really loses it's shape( I think because of the weight of the shoulder strap pulling down on it) and you have to try and hold up the sides to reach in and get what you were looking for. Other than that, I do like her.
And finally the Alexandra. I Love Her! I have (or rather will have after Christmas) 11 of them and I love each and every one. She is the most comfortable bag I have ever owned! It fits great on the shoulder, not too heavy, plenty of room, and will somewhat hold it's shape when searching for your stuff inside.
Therefore, I suggest the Alexandra!
