To say this is a modified version of Simplicity pattern #4111 is an understatement.
I shortened the sleeves & took out some fullness, rounded the neckline, ditched the elastic beneath the bustline, made the ties longer & wider (and still not wide enough, it seems) I added about 2" to the length & about 1" on either side to the width. I think the only part I kept the same is the top front pieces - the boob bits.
The fabric is my favourite part of the whole thing - but it was noted by some friends that its the expanse of pale white/freckley chest skin that makes the top "sizzle".
After seeing this photo, I have to wonder if its the wrinkles from being caught in the rain & then tossing the shirt to the ground that gives it that extra edge?
