Women's Denim Lightweight Jacket 
"COMMANDING OFFICER BOOBY K-S PATROL"  Patch on left sleeve
Both full zipper and full snap for closure
Armpit to armpit across the front measures 46'
Bottom of jacket has partial elastic.   It measures 47" lying flat and has a stretch to approximately 42"
Length from top of shoulder to bottom 27"

I've listed this as an XL.   That is what it measures as.   The label (see pics)  says 4XL.   That is not accurate for U.S. measurements.
Great jacket in good condition.
