SO cute, only worn three or four times (it's a little too big for me so I just bought the exact same top a size smaller). Seen on Aritzia website here: https://www.aritzia.com/us/en/product/shine-bustier/102468.html?dwvar_102468_color=1274#fs – "This is a square-neck bustier with darts and princess seams for shaping. It's made with luxe high-stretch satin with a high sheen."
