St John Collection Knit Jacket and Original Shell Sweater Suit Blazer Size 8 MINT Condition. Royal Blue. The shell has gold embellishment but even in the sun, I was unable to capture the sparkles. The shell also has a shoulder zipper. Beautiful Santana knit jacket by ST. JOHN COLLECTION. Jacket has five buttons to close. There is a nice tailored pleat down the back. There is no flaw or stain and it is in EXCELLENT CONDITION. It looks brand new inside and out. Jacket measurements: Bust: 38 inches Waist: 40 inches Width at hem: 40 inches Front shoulder seam to hem: 24 inches Outer sleeve length: 23 inches Top measurements: Top to bottom Length is 21” Underarm to underarm is 19” Shoulder to shoulder is 14” I think a medium could wear it even though marked a small since it is a stretch knit.
