I don't know about you - but that collar doesn't look sensible to me!
This lovely jumper is from a late 1930s Stitchcraft Magazine, and was knitted up in angora crepe. Sounds yummy! It has a decorative ribbed design that forms a yoke across the shoulders and a 'V' in front.
To fit a 40-42" bust, using fingering weight yarn on 3.75mm and 3mm needles.
