Vogue 1440, a Donna Karan design that I gushed about here. I really think this little blouse is the highlight of that pattern, not the jacket thing. (I promise my hems match up!! - drives me nuts when that happens in photos)
The only change I made was to make the darts about twice as wide at the bottom, tapering to the bust point. It was just a smidge too tent-like as drafted. I think it still has a nice fluid shape while helping me avoid pregnancy questions.
Everything is finished beautifully, too, both inside and outside (thanks to the pattern instructions). There is a fair amount of top-stitching, which you can't see well on mine since it is white on white. My fabric is a cotton/linen from JoAnn's. It was nice and cool to wear yesterday (it's 90 degrees this week already!)
Oops, you can see my cami a bit on the right up there. I wore this with a nude X-back adjustable bra and a cami that I retrofitted for this top by tying the straps together with some heavy duty thread. ;-) I think I would have been fine without a cami, but the shirt was see-through enough that there was a distracting line where my black pants started. I'll have to experiment with an outfit that wouldn't require a layer underneath, to maximize the cool cotton/linen factor.
I also like the detail of the covered button placket. The only interfacing is in the collar and collar stand. I used silk organza, and it lays very nicely, definitely the best result I've had with a collared shirt behaving. I'm glad I didn't use fusible.
