My all-time favorite black bag ever is my Marc Jacobs black quilted Stam. Its hard to beat, classic and timeless.....
...but for your favorite, being a slouchy hobo with awesome leather, I'd say a Rebecca Minkoff Black Nikki (you can find them for reasonable prices on eBay or bonanzle), or the Balenciaga Black Day hobo (much higher price point, but an excellent bag!!!!)
It's nice to hear the day hobo gets a vote. Just purchased one over the weekend. It looked way too pretty to pass.
