I vote for the brief! I have one with RH in cafe and I LOVE it. Of course, it does depend on how much you want to carry. The brief does hold heaps, but no where near as much as the WE.
Thank you for all your replies. I choose brief. As I like weekender a lot, I don't see myself using it as an every bag. But I will definitely get one in the future. Maybe sage from SS08
