Button up in the back muscle crop top

Black and white striped muscle T looks amazing wear w high wasted 70s jeans and wedges maybe more of a crop top for bustier girls. Purchased it at Saks Fifth Avenue unfortunately it doesn't have a size I'm a size 4/6 and if I wear high waisted jeans no skin shows buttons up in the back 19 inches long from shoulder to bottom of shirt. Purchased at Saks Fifth Ave.
