My first was the Proenza Schouler PS1 Keep-All I bought after I graduated. It was an impulsive buy and I didn't do nearly as much research as I should have. I love the bag for what it means to me, but I don't love the bag for how slouchy it is; it's virtually impossible to keep files or my laptop upright in that bag and creases have formed where the handles are attached to the back. I don't plan to sell it ever but given the chance, I wouldn't make this purchase again.
