I know this is pretty modestly priced but mine is my black lambskin Lady Dior. It is my absolute favorite bag that is always a treat to use and a total pick me up. It was a little under $1400 when dh bought it for me.
The bag in my signature is my most expensive to date. Wayyyy more than I ever thought I would spend on a handbag - especially denim! But I loooove it to death and have been using it every day since I got it in May.
