If you love the style of the bag and wants to get it in all the skittles colors that are available out there, WHY NOT?! I can see myself with a mono speedy and a damier speedy in the future as well as lots of B-bags in those yummy skittles colors.
i totally agree with what everyone else has said... if you love the bag then get it... who cares if you have it in other colours!!!! its just great that you can swap them around etc... to go with what you're wearing!
No problem. I have the Le Fab and L'Epanoui GM in white! I'd love to see you wearing your collection, by the way -- I'm a big fan of that! Showcasing of bags aren't as fun as seeing people wear their gems.
