From Trend Patterns:
Our oversized sleeve top has been designed by us from looking at the trends from the AW16 catwalks from New York, London, Milan and Paris fashion weeks. We were inspired by the big, voluminous sleeves.
This pattern is best used with a lightweight fabric. A cotton would be a good choice or be daring and do something sheer, for example black tulle would be beautiful or an organza to be both sheer and hold the shape. For a more dramatic silhouette use something slightly heavier.
