This is an amazingly unique find!

A collarless gabardine wool like short coat with ribbon like fastener accents.  

The Union Label is the ILGWU AFL-CIO National Recovery Board Coat & Suit Industry Label which was used between the 1950's and 1960's.

There is no size or material tag but based on feel I believe it to be a worsted like wool or wool blend and based on actual measurements I believe it to be a women's size medium or large.  Please go off actual measurements to ensure an accurate fit.

The only small flaw is at the trim on the collar area.  It has some slight rub wear.  It is still a great vintage piece!

Actual measurements:

Armpit to armpit approx 22. 5"

Shoulder seam to shoulder seam approx 17"

Across the waist area approx 23. 5"

Sleeve length from shoulder seam to cuff approx 20. 5"

Length down the back approx 32. 5"

Mannequin measures approx 35" Bust 27" Waist 36" Hips
