I do not own any KS bags but recently saw the Gold Coast line at Nordies in person and thought wow! They look amazing and really well made. But since I do Motown any I wanted to now how well they do hold up? I see them all over ebay and wondered if they are good quality pieces that last? Any input would be great. I was looking at the Maryanne and the Georgina I think it is called. Them I also saw the Sierra online as well. I do love her clutches. They are very unique and playful and fun. Thanks!
