Vintage Spectator petite Medium or Small top

This is an awesome reposh that unfortunately just BARELY fits me! It's so cool I wish I didn't have to part with it. It was sold to me as a Vintage Spectator top and is in a PETITE Medium size. It's super classy looking and I bought it for office-business casual wear. It's got that 80s businesswoman feel and IT HAS POCKETS!!! Snazzy button detailing and overall a sweet pattern. It would best be suited for a true Small to a Medium, but I feel it's on the smaller size.
