This tiny little striped baby jumper, inspired by the effortlessly chic Breton knits, is fun to knit for your little one or as a little gift. Fastened at the shoulder with some snap domes, and with enough room to move in and grow into, this is sure to be a firm fave. 

I picked neon coral and grey for this sweater because I absolutely love grey, but also wanted a bright splash of colour to perk up the pastel garments that are so readily available. Neons and neutrals are a winning combo, and these match perfectly with my two-tone Neon Newborn Socks.

This sweater knitting pattern is worked in stripes, seamlessly to the underarm, and then the fronts and backs are worked flat separately. The sleeves are worked seamlessly in the round, and then sewed in place.

Let’s get knitting!
