It is the silk slip from Knitting Lingerie Style! I finished it a long time ago and finally got the pictures too. actually made two since.
It’s a great way to use your last shin of leftover yarn! The cleavage is kind of revealing and I didn’t follow through all the instructions in the pattern, really had to make the cups larger (maybe because of the yarn), also one should be careful with the lace placement, those holes in the knit might end up where you don’t want them. So instead of knitting 4 repeats of the lace pattern, I’ve only made 3 but after knitting some more simple lines. I also used a how to from BurdaStyle for sewing the darts: http://www.burdastyle.com/howtos/show/867
I’ve made a narrow rolled hem at the bottom and it has hooks and eyes in the back slit for closure.
