It's not apparent in the picture I'd posted. It's probably more appropriate to call this a poncho *shirt* because it has long sleeves, similar to H's long sleeved silk shirts. The sleeves have cuff links too.
S, how lovely! - this is a much more functional way to wear a mousselline material than the shawl! Can't quite tell from the pictures that there are sleeves and also cuffs on the sleeves.... Action pics if you are modelling it. Thanks!
