I just got mine, in navy. I'm planning to pair it with medium wash jeans (like the color the model is wearing), my slightly faded black jeans, possibly my grey trousers, and black slouchy trousers. And I think it might be amazing with the new orange trousers I just bought. I've not tried it with skirts yet. I think it's a little too long on me for most of my skirts but it might work with, say, the VC tube skirt.
What I'm not planning on wearing it with is my dark wash blue jeans. I think that's too matchy for me.
Oh, and I don't plan to layer under it. I think I'll layer OVER it though - it's thin enough to fit under my blazers. I think it'll be fab with my grey and fuchsia blazers, and possibly also the white one.
