Hi! I really like the look of the alexa and I want to buy one but after reading more about it on the net, it seems that some owners are complaining of the quality and that it's not as good as it used to be. For example, some have complained about stitching coming off and the color of the lock also coming off. For the price of the bag, is it still worth it? Also, did any of you buy your mulberry bags from erica of hgbags? Is she a reputable seller? Thanks!
