I have it in orange and I adore it. I'm a fan of colorful handbags so it's perfect for me, if a bit large.
I remember the first time I saw it. I was walking up 57th street past the Prada between 5th and Madison and it stopped me in my tracks. It was the first Prada that ever called my name.
This does not mean that it necessarily calls yours.
See how it looks with the clothes in your closet. If you need to buy new clothes to wear with it, that might be a sign that you don't really need it.
Good luck with your decision.
