On my trip to Chicago earlier this year, I saw a really cute knit top in a ribbon store we visited. I love how they pleated the neckline on the top. Here's a photo is took
I took my pattern and sliced the neckline to add more fabric for pleating. Since I didn't want the entire top/hem wider, I just slashed and spread partially down.
Here's a photo fo the original and modified front pattern piece.
and here's a photo of the back pattern pieces.
and here's the completed top, front and back.
