EUC Topshop Bubble Puff Sleeve Open Back Blouse

Super fun Topshop blouse with so many interesting little details! The puff/bubble sleeve is split with rouching, the open back has a tie and shirring at the bottom, there is also a side zip and bust darts. Tagged a size 6, measures about 35” ptp (but because of the darts in the bust it likely accommodates a little more), and 29” at the waist.
