This three-piece suit is darling and oh-so-warm for baby. The designs are knitted using worsted weight yarn and sizes 5 (3.75 mm) and 7 (4.5mm) straight knitting needles and a set of four double-pointed needles size 7 (4.5mm). The jacket features a button front and contrast-color sleeves. The leggings have built-in boots. The tie-on helmet has a pom-pom topper.
