Swinging on the Gate
Simple drop-shoulder linen stitch jumper worked on the bias plus a loose roll-neck cowl collar. Can be made with plenty of positive ease or more figure-hugging.
Skills you should already have: knit, purl, slip, basic intarsia technique, PUK (pick up and knit), mattress stitch seaming. Increases and decreases are explained in the pattern. Additional skills for the cowl: provisional cast-on and grafting (Kitchener stitch).
The directions contain the original colour scheme, but also tips for coming up with your own, as this pattern is great for using up oddments / scraps!
