Coach Hailey, then after a few more Coach, LAMB and Kate Spade my first 'premier' designer bag was an LV Speedy 25. I have no desire to go much above that in price (I would like an LV Totally PM though).
Coach was because lots of people here have them, LAMB and Kate Spade I stumbled on by accident, and LV because it's timeless and iconic (Speedy has been made continuously for 80 years and never goes out of style).
