Hello, ladies! Pardon me for stopping over from BV, nice to meet you all! ... I am seriously considering a used-in-good-condition medium multicolored Muse Two ... and I have a long strap lined up for it already if I should decide to get the bag. Some of you have commented about it being 'slouchy' ... I saw a pic online of it being pretty 'puddly' ... is this true for the medium?
