Easy design with caveats

This describes itself as a simple pattern and it is, however beginners beware! The pattern had 1 facing when a pair are required. It later discusses plackets  which are the facing! There is no advice for button placement

I emailed the company and they are changing future pdfs apparently, they were very helpful.

I added interfacing to the plackets and used bias binding around the neck and collar before stitching the plackets.

However experienced sewers will work all this out and I loved the simplicity of the design with the off centre buttons.
