Redone upcycled Nike corset top

Such a cute top that has been made from something else Nike. There are NO tags (material, care, etc) since it is 100% handmade. It is completely adjustable and the measurement listed above is pulled the smallest. The shoulder straps are completely adjustable as well. It is shoelaces that cinch the corset and function as shoulder straps. The seams all feel like a light boning, but I think it is just the seams. Got this from a festival and wore it once. I am listing as a small/medium but please refer to the measurements above.
