Interfacing pattern pieces

The ready-to-wear shirt's interfacing was cut on the bias, so I marked my patterns accordingly.

 

The ready-to-wear shirt did not have interfacing in the point of the collar, so I've cut off the corner of my pattern.

 

In addition, the inner collar stand did not have interfacing in the 1/2" seam allowance of the long edge nor in the 1/4" seam allowance around the curve.
