I have been sorting out my wardrobe and unearthed a beautiful wool/cashmere poncho. It is very elegant - think Donna Karan/Tod's rather than peruvian panpipe busking group.
Haven't worn it for a few years - iirc, ponchos were all over the place in 2004.
Would it be a huge sartorial mistake to layer it up over say jeans, long sleeve tee/merino jumper and boots?
