I voted for Antigona having seen both about a million times. Well, seen the Nightingale a million times, trying it on, taking it off. Going home, and then coming back again the see it further. The problem with the Night is that I never really liked it. Sure, all that leather is yummy but a few things about it turn me off. The shorter handles, the shoulder strap that seems to be so thick (why is it so damn thick?), and the lack of hardware for some bling action.
So yeah, I went for the Khaki Antigona in medium and BOY am I ever happy and THRILLED with it! Who knew? A former Balenciaga lover like me could fall for a structured bag? Paid full price plus tax for mine and would do it again for the right one. The Antigona has handles of a perfect length, shoulder strap with a good thickness to it, but not so much that it feels like a pillow is sitting on your shoulder, AND the basic shape of it drives me crazy.
It's finishes off my look with a touch high end luxury feel. The look is of imeccable style!
The Nightingale simply does not. Your decision should be based on what you currently have in your inventory....if you have a lot of sloughy bags, why not go for something different?
Hope this helps!
I was going to get the nightingale last xmas but I have been using big bags for a while now so I finally pulled the plug and got a shiny antigona in small. It's a really thick calf skin material so I don't think it'll slouch much. I've only gotten it for two weeks and am really loving it.
