My coworker came to me today with a bag that would be considered one of Coach's Classics/Legacys. She purchased it at a thriftstore last night for $3.00. The purse has to be at least in the $125-$150 price range. Ironically, I was carrying my Stewardess bag today, which prompted some questions from her. She showed me the turnknob thingy on the front, which was badly tarnished (someone abused this poor bag ) She was asking me if there is something she could use to spruce up the hardware. I thought this would be a question for TPF. What can she do to restore this classic bag ladies?
