I've had the Popincourt Long since about January, and I love it. I always wear it across the body, although you can also shorten the strap to wear it over the shoulder as well. (I am 5'4'')
I primarily use this bag for casual situations/weekends when I want to have both hands free (like when I'm shopping) or when I'm somewhere where I might not want to put my bag down on the ground or floor (like at an outdoor sporting event, in a pub bar, etc.) I think it is an extremely useful bag; next to my Batignolles Horizontal, I probably use this LV the most. I highly recommend that you try it out. Good luck!
