Purchased from Baycrews and worn once for an event. It has been dry cleaned and stored at home. Made of triacetate, the fabric can be worn in all seasons except for the peak of summer and winter. I think it's suitable for formal occasions, school events, and recitals. I usually wear a size 36 in Deuxième Classe, but this one was a bit large, so I chose a 34. Here are the approximate flat measurements (measured by an amateur): Waist: 32 cm Total length: 84 cm
