Pattern includes sweater, skirt, hat, and leg and wrist warmers and pants in case you prefer then to the skirt.

Patterns are all knit flat. Sweater is worked bottom up and sleeves are set in.
Skirt is knit side to side with short rows.
Hat knit from band up and leg warmers are knit top down.
It is not a difficult pattern, even the color work is slip stitch, using one color in each row.

I worked from stash but used most of the skein of Knit Picks Brava sport in the red color for the outfit The other colors used less but am not able to say how much. Grey is probably the 2nd most used.

Gauge is difficult to give but here is the best I can do:
The k2p2 rib = ¾“ or 2cm for one repeat. 4 repeats equal 3”.
Hat in stockinet: 5 stitches in one inch.
