Aritzia Babaton Contour Muscle Tank, size medium, in shade Coffee Bean. Shade no longer sold at Aritzia and shirt has never been worn. __ A strong favourite, this is a tight-fit tank with a high crew neckline and double-layer fabric for a supportive fit. It’s made with Contour — luxe, ultra-flattering fabric coveted for its smoothing effect and second-skin feel. Nothing more essential.
