Got right gauge. Made some modifications:

1. Omitted mittens and started sleeves with light yarn to match wider light bottom edge. Sleeves and body now are the same length.

2. Started collar with 3.5 mm needles, changed to 3 mm needles as in pattern, then finished 3 rows with 2.5 mm needles to have tighter neck edge.

3. Made two rows of garter stitch on all edges (sleeves, bottom, neck).

Not the best yarns for this project, but will see how it goes.
