I agree. Show the clutch open. stuff it with some tissue paper or a plastic bag to show how it would look with "stuff in it".
It might be helpful to explain just where the red mark is. Is it on the outside, or is it a lipstick mark in the lining? Where it is makes a big difference on a white purse. I think you mean its in the lining, but someone might just not pick up on that. what about adding a decade to the time, and you could get rid of the "and" in black and white for more room.
If it doesn't sell this time, i would hold off and wait til you had a "batch" of things to sell at the same time so the hits from the other items would draw into it too.
