This is the Linen Côte d'Azur Tee from J.Crew. It's currenty on sale and has been featured on several blogs already. I'll just add a couple of more photos to the lot. I found the fit to be true to size and I like the linen knit, although it is sheer. The jacket, skirt, and clutch are repeat items seen in my recent posts, here, here, here, and here.
My favorite way to wear it is with a pair of faded jeans. :)
