Luxe Long Sleeve Crewneck Top

It's really difficult to discern fabric content online but this tee is a super luxurious fabric, not your typical tee. Incredibly soft on the skin and has a modal stretch to it. Nice length (not cropped and not too long) and the sleeve length is good too (ref: I'm 5'6"). I bought both the black and the white and the white it a little sheer but I plan to wear it as a layering piece so that wasn't an issue for me. The black isn't sheer and a nude bra underneath doesn't show. Runs large in my opinion -- I usually wear a small in most tees and had to return it for an x-small.
