In fact, I love greyish bags. They always catch my eye! There is so much variety in grey shades that it is possible to justify having as many as you like so long as they are different!
Not unpopular - It's GORGEOUS! I was this close to getting it in the med also, but couldn't pull the trigger b/c I had just purchased ecru.
Plus, I've seen stuff that was supposedly "unpopular" and lingered on shelves get worn by a celebrity and then a buying frenzy ensued (read: Jessica Alba blue soft & chain).
Be still my heart....your bag is exactly what I am looking for--the softer caviar leather and the most beautiful grey..but maybe in a jumbo, ok a maxi will do too. Congrats and wear your bag joyfully!
