Hi everyone! I am new to Coach and I am completely in love the Black Leather CARLY (not the large one, but the regular sized one). I have not yet tried it on IRL, but I have a few questions to all of you Carly owners: * Is the bag really heavy? * Does the strap STAY on your arm, or does it slip off? I am looking for a one compartment, one strap bag, and this one seems to be perfect. I am having shoulder surgery next month, so I do not have the "luxury" of switching shoulders when I am wearing my shoulder bag. I wear my bag on one shoulder only, so I am looking for something relatively lightweight. Any guidance? Thank you all so much!!!
