I am really lusting after a reissue & want to buy one because they are SOOOO gorgeous !!! I love the MM lock, the chain, etc ~ they are truly devine!!! But I need guidance. I am somewhat new to Chanel ~ well not really new to Chanel ~ just A LOT less knowledgeable than most of you ladies. I just go in, see it, love it, buy it...so I am waaaaay uninformed . I want to know the measuremnts for the reissues...I know the sizes I am interested in seem to be 226 or 227, but what is the difference? HELP...please & many, many THANK YOU's!!!!!!
