All of these cape blouses can be found at Asos.com at various prices. I did 'cape blouses' for an assignment for class as a trend prediction for this summer. I happily have noticed cape blouses in various styles in stores everywhere.
I love the cape details that designers have added to simple, more casual blouse basics. Button down fronts with possible cape plackets or cape shoulder details. I looove them. (especially the 1st one which is on sale right now for $40)
