I jumped on that pattern pretty quickly, because I wanted the black and white striped top for choir this month.
I shaved 3/8" off the top portion of the back raglan seam, then I added 1/2" to the neckline all around. I shortened the sleeves SIX INCHES, then narrowed them by about 1/2" on both sides at the bottom, tapering it out at about the elbow.
It's a ten minute top, meaning I made it in ten minute increments.
I like the fit at the neckline much better, but it's still not perfect. For perfect, I think I need a teeny dart at the top of the shoulder on the sleeve portion.
I was surprised, too, at how long the sleeves still were. I was shooting for 3/4" length...they're a little past that, even with the amount I took off.
But this one is definitely wearable...it looks good under a jacket or an overshirt!
