This is a Roman Model Dalmatic with Sleeves open. The dalmatic is to match the Chasuble Set - D16 model.
The material of the garments is made of damask fabric and the orphreys are made of black silk fabric. The dalmatic comes with a matching deacon stole & maniple. The interior of the dalmatic is with matching Satin Fabric.
The Dalmatic is the outer liturgical vestment of the deacon. It is worn at Mass and at solemn processions and benedictions. The colour of the dalmatic should be the same as the chasuble the priest wears as per the liturgical colour of the day. (source: www.newadvent.org)
