i have a trevi pm but i want a more spacious bag..i like everything about the trevi pm except for the space, that's why i have my new saleya mm..but right now, i'm confused if i want to keep my saleya mm or return it (because i received some feedbacks that saleya tend to sag and lose it's shape over time) and purchase a zippy wallet in damier ebene to match my trevi pm, instead..but still, i'm thinking of whether keeping the saleya mm or return it, purchase a zippy wallet for now, and add to my wishlist a trevi GM so i can have a more spacious bag in the future..i plan to keep my trevi pm because i really like it except for the size, but i want a trevi GM because of the space, and it still has the look of a trevi pm (in larger version), though i'm not sure if it looks as stunning as a trevi pm....oh, i'm confused..help me decide pls..thanks
