This isn’t just any brand new jacket. It was designed by the legend singer Pharrell. He is extremely creative! I’ve never in any other collection have seen a jacket like this! I cut off the fabric tag bc I wore it once and the tag showed thru the jacket! However, I snapped a shot of it in my pictures. It’s so delicate. Most likely a poly blend. The is a size small but is a little oversized so it can fit a medium as well. 528HZ on the back means the perfect musical note. Whatever that is to Pharrell. Never been worn. Only tried on.
