The version shown in the first photo is available in the Well-Dressed Bunny pattern, which includes instructions for long and short ears, with 3 outfits: a hoodie, a pinafore dress, and a vest with jacket.
The version shown in the second photo is available in the second edition of Fuzzy Knits, and is called Mister Bunny. In this version, some of the toy shaping has been altered, and the outfit redesigned to fit better. The Well-Dressed Bunny pattern will eventually be updates to include these changes.
The bunny is knit from 50g of worsted weight yarn on size 6 (4mm) needles. The vest and jacket are knit from sport weight yarn on size 3 (3.25mm) needles.
In the Mister Bunny version found in Fuzzy Knits, the Waistcoat back, page 20. Row 16-17 is incorrect and should be as follows:
Row 16-17: repeat rows 14-15 (24 sts)
