I designed this simple baby sweater crochet pattern for my newest niece, Navy Jayne. The Plain Jayne sweater will be a wardrobe staple item. It’s gender-neutral and can be worn in so many ways. Making a tiny sweater is the perfect bite size project. Even with the lightweight yarn, it works up in a flash.

I always gravitated towards garments that were “simple”. That could be made in panels then sewn together. After working a few top down sweaters I’m hooked! I love that you don’t have to seam anything together.
If you’ve been hesitant to try an all in one sweater this pattern is a great starting point. They really are easy to understand once you’ve made the first one.
The sweater is a raglan style. That means it’s crocheted in one piece from the top down and has increases in specific places. This creates 4 distinct points that create the front, back, and 2 sleeves.

Another type of top-down sweater is a round yoke. That means that the increases are spaced evenly around to create a smooth curve. The Over The Top Crop Pattern has a round yoke.

I wanted to make one for my other sweet niece Emmy. She’s wearing the 24-month size made with the Hawthorne Yarn from WeCrochet. I love the subtle color variations. It’s a budget-friendly yarn and is machine washable (yay!)

Let’s get started on the crochet baby sweater pattern.

This sweater is adorable! Please consider an adult sized one in the future. Thanks for sharing♥
Thank you! And I totally agree. I’m planning to slowly add more sizes for this sweater.
I’ve been looking for a nice simple baby jumper pattern and thought this might just be the one! However I can remember how tricky it can be to get clothes on small babies and worry the fact this has no neck opening might make it difficult to pull down over a baby’s head…..and then there is the problem of getting it off again. I appreciate the yarn is lightweight but sock yarn can be quite firm also. Do you have any suggestions for making this with a neck opening please.
Hi Maura,
I totally understand your concern. If you want to add a button at the center back of the sweater, you could skip seaming the ribbed neckline together. After you work round 1 of the body you could join with a slip stitch. I hope this helps!
