Personal opinion: sometimes a jaunty hat does not improve an ensemble....though it does drag your eye away from the standard issue white jeans. However, if you can look past the styling to this lovely lace stitch jumper, you will not be disappointed.
Knitted King Cole Big Value Super Chunky, the lace pattern makes the super chunky yarn appear delicate. If you were looking for a slightly more refined version of this jumper you could try the muted colourways of King Cole Timeless Super Chunky. All knitted on 8mm and 10mm needles.
