RBX womens size L pale green workout top cross back straps, sheer details

This little workout shirt is light as a feather. Very, very pale jade green, with a scoop neck. The sleeves are sheer, and the top back is also sheer with a partial cut out and gray cotton double-cross detailing. The fabric appears to be a wicking type athletic fabric--- shirt is marked X-dry. This one doesn't have any tags, but it also doesn't look like it was worn. I'm calling this a size L to XL. See photos for tape measure details; 19" arm hole to arm hole. Price reflects the mystery, but is firm.
