Joseph Ribkoff Womens Scoop Neck Solid Asymmetrical Blouse Top Blue Size 6

Joseph Ribkoff Womens Scoop Neck Solid Asymmetrical Blouse Top Blue Size 6. Preowned good condition. Not sure what the little squares are on the sleeves. I did see similar top that had sleeves roll up and button, so not sure if there should be buttons there? Its very dark blue. There is a small area near back shoulder that has some pilling or something. Otherwise very nice condition.
