Honestly....(now it depends on the Fendi) but I'd vote for a Fendi. I have a white leather/fur Fendi that is gorgeous. The leather and satin lining just can't be beat. LV is more practical and sturdy. Fendi is quality and class.
i like the shape of the cabas a little better...it's a smidge taller and i think that balances the shape better. and i don't like the fendi logo personally. but you don't have to worry about dirty vachetta with the fendi...hrm.
