Obsessed with this shirt, it is the perfect light layer and so versatile! I have a hard time finding button-ups that don't overwhelm my frame or look too bulky at the collar – this is oversized but cut in a way that it is super flattering and the fabric drapes wonderfully, the cut in the back is really flattering too. Love that it's 100% cotton, fabric is so soft, light and breathable. It looks wonderful tied, tucked in or used as a cover-up. It definitely runs large as that's the style; I'm usually an S/4 thought sometimes XS in tops and am 5'6" – got the XS, it's perfect. Got it in two colors (taupe and white, which is just the right amount of sheer and not too see-through) and will be wearing it constantly!!
