Express Design Studio low-cut kimono-style shirt

EUC, no defect besides a stain on the left cuff as shown in third to last pictute. I don't know the sartorial term to describe this kind of shirt, but the left side of the shirt buttons on the inside behind the right part. I try to take a pic describing this mechanism in the third pic. It is a bit low cut. Medium Size. Approximate Measurements: Pit to pit 18" Length 22" Shoulder to shoulder 15 1/2" Sleeve from base of neck to end of sleeve 30 1/2"
