I have lusted after a black Multicolore Speedy 30 forever. A friend of mine warned me that I may not like it because most of my bags are very structured and the Speedy is not. To prove her point, she sent me a Monogram French Company Speedy 25 of hers to test out. Even in carrying it with a piece of cardboard that my friend graciously laid in the bottom of the bag, I felt like the bag drooped and looked sloppy. But I'm still in love with that Multicolore 30! What are your experiences with Speedys/tricks for keeping them somewhat structured? Do they all pretty much sag? Should I stay away from them altogether?
