Oh, when I walk around, I carry a smaller handbag. It's a smaller profile, it has a zipper, the structure of it makes it difficult to open without me noticing. It has a zipped pocket on the inside, and the flap actually can fit some small stuff. And being smaller, it's still big enough to carry a water bottle and an umbrella with room to spare.
I guess it was just a purse that was in my price range (I don't want to spend too much on a travel purse) and carried everything I needed securely.
I only carry my Le Pliage when traveling from and to the plane. I guess if I knew I'd be shopping, I'd carry the LP so it's not obvious when I visit and shop at the high street shops. But still I'd have a purse separate from the LP.
Cool.
Then, I guess, your decision comes down to if you'd rather have purple or chestnut. I think Chestnut is one of Coach's nicest brown shades and I really like the soft red lining that it has. But, Black Violet is pretty too.
I guess, for me, if I was going to keep a bag as a travel bag, then I would want it to go with a majority of my wardrobe. For me, that means I would need a neutral bag and, hence, I would pick Chestnut over Black Violet. Not sure, if this will help your decision or not...
