Errata:

For the Cape section:
It should be rows 4 and 5 your repeating so you end with a RS row. That would be row #105.

Row 106 (WS): sl1 and purl across but do this while changing to your smaller needle. (Purl off your size 9 and onto your size 7)

Then continue in the 2x2 rib for 2 inches.

Please note: the original design for this cape was for the opening to be asymmetrical (see sketch). If you want the opening to be in the front, as pictured, please re-distribute your marker placement as follows:

Row 3:
Sl1, K13, PM, K2, PM,
K13, PM, K2, PM,
K30, PM, K2, PM,
K13, PM, K2, PM, K14

Row 5 (increase row):
Sl1, K13, M1L, SM, K2, SM, M1R,
K13, M1L, SM, K2, SM, M1R,
K30, M1L, SM, K2, SM, M1R,
K13, M1L, SM, K2, SM, M1R, K14

The increases are still in the same positions (on either side of each raglan shaping) but start later since the opening is in the center as opposed to the original design which was at the side.
