Get the flap. I have one in black and I love it. The camera bag did not fall right on me and felt like it would always be bouncing off of me as I walked (I'm 5'8"). Also, you can carry the flap in three different ways, long strap, double strap and cross-body.
I recommend the first one which is prettier.
The beige marmont flap!! So beautiful!
Thank you all for taking the time to reply, I really appreciate it! There really is something special about the flap style! I need to get to a store asap to try it on!
