Oh dear

My new blue shirt has got mysterious green stains on it about the middle of the waistband. I suspect that dye or something has either come off my jacket or my jeans. The weird thing is, the jacket is grey and the jeans are blue. I would be more inclined to suspect the jeans, but the stains look more like they're on the outside of the material. And now that I come to think of it, the same thing happened to my pink t-shirt, and I don't think they came off. Okay, no light-coloured tops with that jacket in future, then.
