Owned by me for many years, this is a hard to find piece of the original 'Queen of the Mods' Cathy McGowan's collection released by the singer in the 1960s. 

Striking shades of blue and green, and in a medium weight cotton drill - lined in rayon acetate. 

Frustratingly it was missing one of the original buttons (remaining four included) so I had replaced with period appropriate suede covered ones. You may be able to get a better match as the originals are just covered cotton drill, although I think these aren't too obviously non-original.

Really flattering shape, slightly fitted. It's an easy piece of vintage to mix into a modern wardrobe. 

Measures: 

Bust 36" with a little dart room

Waist 30" max

Hips 40"

Length from nape to hem 32"

Shoulder to shoulder 15" seam to seam

Underarm to cuff 16"

Condition: 

Buttons are replacement as above and a bit dingy if you look closely.

Has been cleaned but some signs of age marking to interior of collar - you could possibly soak it. That’s unseen when worn.

Some fade to lining at underarms, and a seam separation to left hand side seam

No damage noted aside form odd tiny slub in weave. Immediately wearable.
