Fantastic vintage mod trench coat from the 60s or 70s.  Outer twill shell is most likely a cotton blend, with white detail seaming.  The color is a rich reddish purple.  Full lining is  white acetate type fabric.  No labels.

Bust is 34/35 inches.  
Waist is 30 inches. 
Hips are 41 inches.  
Shoulder to shoulder seam is 14-1/2 inches across.  
Sleeve is 22 inches long.  
Length is 45 inches from the shoulders. 

2 pockets on the side seams.  I love how the belt goes through the faux pocket flaps.  A minor repair to 1 interior pocket seam.  I think would fit a petite woman best because of the shoulder and sleeve length. 

Wonderful condition.

Mannequin measurements are: 34 / 24-1/4 / 35 inches
