^ As you saw, that is the same bag I'm looking at, but without the texture

You have excellent taste
I KNOW! Great minds think alike! 
Just kidding =)
I've seen it in person & everything looks good ... the chain is particularly beautiful. (I suppose
you want a chain bag from a designer who's also well known for costume jewelry, which would be either of the ones you mention

)
Great point you are making here! I will write that down for future use
The only thing that looked like a potential weak spot to me was the lining ... not that it looked bad, it just looked like the weak point of the bag, the thing that would go first if anything did. I suppose it could also be repaired ... and I don't really care about the logo fabric inside. The zipper was heavy duty & slightly difficult to operate ... probably just needs to be broken in a bit.
Did you see interior pics anywhere online? Would love to see the lining etc...
Actually, that sounds good. I think better the lining than the hardware or leather!
Bear in mind that this bag is on the small side ... all the major items I carry fit inside without a problem, but I would definitely have to watch it, no cramming in extras & certainly no water bottle
I guess I should say what those are ... a smallish wallet, a largeish lipstick case, makeup bag, phone, keys, pillbox.
Another little disadvantage is there are absolutely no inside compartments. The bag I have now has 3, and they work perfectly for me ...
Hm, yes, definately not a bag you want to overstuff (not that I am talking about myself here
noo, I haven't broke a zillion sport backpacks because of overstuffing
). Would also give the bag a weird shape I guess.
But I think it is perfect for the days you want to carry only a few items with you and it can be used as an everyday and evening bag!
However, the bag is very beautiful, and I am very picky ... what's a girl to do
She has to BUY IT!
