Rag & Bone // The perfect black bag

Last night I had some girl friends over, and we got to talking about designer purses (I swear, we usually don't really talk about 'feminine' stuff like this, not that there's anything wrong with it).
I'm not sure if this is universal right now, but there's a huge trend for Michael Kors everything in my city. While I actually do own one of his bags, I'm not sure if I love all his stuff, especially the bags with the big MK or the bling watches. We also discussed Celine bags, which I don't have a strong opinion on, but often just remind me of southern fashion bloggers who wear huge bubble statement necklaces.

For my own taste, I kept thinking about these Rag & Bone bags I would occasionally see advertised on Shopbop. I like them because they are incredibly simple and sleek in design, but have just enough detail to be interesting.
