I’ve updated this older pattern for a T-shirt with raglan sleeves and a boat neck. It has a close-fitting silhouette and I also narrowed the sleeves and the neckline, so that the T-shirt won’t fall off the shoulders. You can get an updated version of this pattern here: Pattern for women’s T-shirt JACKIE.
Recommended materialThe pattern works great with thinner elastic materials. Choose some kind of quality cotton knit with elastane or lycra. Try to avoid 100% cotton knits. They can get stretched out quite easily, so they are not suitable for women's clothing. I would use this type of knit for kid's pajamas (maybe). I have knits featured in this article from Důmlátek.cz. This store is huge, you can take a look at knits with polka dots or all knits with patterns, for example.
Different T-shirt variationsI’ve made this T-shirt with a small variation, compared to the original version (which has facings, instructions here: How to sew a T-shirt with raglan sleeves and neckline facing).
You can also take a look at sewing instructions for my other similar pattern here:
I’ve finished the sleeves of this T-shirt with cuffs (wider stripes of knit) and its boat neck is finished in the simplest possible way.
How to sew the T-shirtYou can sew this T-shirt with a regular sewing machine (if you don’t have an overlock, which is an ideal choice). You might find this article useful if you are going to use a regular sewing machine:
Sleeve pieces preparationLet’s modify the sleeve pattern piece first. Since I’ve finished the sleeves with the cuffs, I had to adjust the pattern a bit. I wanted to make the cuffs 5 cm long, so I had to shorten the sleeves by 5 cm (measured from the edge of the sleeve - seam allowance is not included).
