I used New Look 6849 to make this tunic. The pattern appears to be out of print since I can't find it on the Simplicity website. I've used it several times already and find it to be a great starting point for a woven, not-button-front blouse. The only changes I made were to shorten the sleeves to a cap-sleeve and I omitted the back darts for a looser fit that doesn't need a zipper.
The fabric is from Sawyer Brook. It is out of print now, but it is a very interesting rustic silk. It looks a lot like linen.
