I tried on the XL, and it is super wide. I have seen a lady wear it, and it's so wide, it's the type of bag that hits things when you're in a small store because it's so wide. I personally would find it annoying.
If you want to get another bag, get another GST! I have six in different colors and love them! I rotate through them. Pick another color! The GST is just classic! So gorgeous. It is still my favorite of all Chanel bags.
It's super easy to rotate through my GSTs, as I just transfer my stuff to the exact same pockets!

I vote get another GST! Totes will come back, so you'll be ready!
