You echo my exact sentiments when I received my classic flap! I had wanted it for a few years and everytime I see it on magazines or on ladies along the streets, my heart skips a beat. In fact, I totally couldn't sleep the night after I placed an order, was irrationally excited. Well, not until it arrived and I ripped open the fedex box, saw the flap and thought "is this it? What I spent $2600 on? Am I out of my mind?"
To make matters worse, mine came with a loose stitch. It just adds on to the buyer's remorse. I didn't fancy the ghw against caviar leather either, although it has exactly been what I loved all along. Eventually I managed to exchange it for a silver hw flap due to the poor stitching.
And I didn't return the flap because i convinced myself that it IS a classic and I just can't return it! If given a second chance, I won't have even purchased. Sad, but true. I couldn't figure why the buyer s remorse either especially when it a bag I had been covetting for the longest time. Urgh!!
