I am looking at the denim speedy Let Trade has for sale..and really wanting to purchase it ...but I've not been able to try one on IRL....so I'm a bit hesitant..:s Anyone who owns this bag...can you help me decide... Is it big enough (size wise is it like the regular speedy 30, 35?) Is it durable...does it get dirty easily? If yes..is it hard to clean? Is it only really appropriate for casual wear..or can I us it when I dress more classy (social party like)? What do you not like about owning this bag?? Thanks!!
