All in all I think it turned out as I had envisioned it to. The keyhole necktie is my favorite bit. It looks so clean and finished, too!
I also did a catch stitch for the first time on the sleeves. The thread color was a bit challenging on this blouse because if I used a white thread it would be very obvious on the black, and black would stand out on white. So I chose the lesser of two evils and went with white. I tried to make my catch stitch as small as possible, but still substantial enough to hold everything in it's proper place. I think it's mission accomplished. Here you can't really see the stitch where the white is:
P.S... this blouse is super slippery and doesn't like to stay tucked into a skirt. Does anyone have some tips on how to keep it in it's rightful place??
