This is a spanish cut (triangular bottom) Roman Dalmatic. The material of the garments is made of silk fabric and the designs are embroidered with different shades of metallic gold yarns on the silk fabric. The dalmatic comes with a matching deacon stole & maniple. The interior of the dalmatic is interlined with soft felt for fullness and lined 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)
