The deep green two-gold button blazer comes with three gold button sleeves, with the Sakdidej crest on the breast pocket. The crest divides into three panels. On the upper right side is the Phra kiao (coronet) on pink background, while on the upper left side are Chakra (disc) and Trishula (trident) on yellow background. On the lower half panel is the then-Prince Prajadhipok’s personal arm: three arrows on green background, representing Wednesday, his birthday.
The Sakdidej lapel brooch sits on the right side, above the breast pocket. This particular blazer once belonged to Rongsanit Jotikasthira, one of King Prajadhipok’s royal servants.
