+1personally i just love the size and shape of the saint germain
It kind of depends on what you are going to use it for. I love them both. I think Twice is casual and saint germain bb dressy. I have Twice in noir and it's the best bag I have.
Both are nice, but the St. Germain could be worn out to dinner etc, whereas the Twice is just a great cross-body daybag.
