I am wanting to buy a chanel cambon black tote, but I always have problems with the straps on purses, if they are so short to where they fall off your sholder, it bothers me to where i wont use the purse. so i was wanting to know which tote is better before i spend alot of money on them: the medium tote or the larger one? or are they both short?... if they are both not good, then any suggestions on different kinds of totes.. thank you! oh and i am looking on a website called 7starhandbags.com because the totes are alot cheaper.. does anyone know if that is a good reliable site to buy handbags from?
