Classic black St. John Sport jacket, size petite

This is a black cotton velour St. John Sport jacket with slanted pockets. There are two grommets where the sleeves connect to the jacket and a silver zipper with the St. John logo. The St. John Sport by Marie Gray label is inside the neck and there is a St. John satin patch on the back neck area also. The size is P. When choosing a size category, that was not an available choice so I chose 0P. It is 21 1/2" from shoulder to the bottom of the jacket and the sleeves are 22" long.
