This is a sewing pattern and tutorial for a T-shirt with a deep open chest neckline.
This type of neckline is often seen in anime-style costumes and cosplay outfits.
Bias tape is used around the chest opening. Changing the color of the bias tape can make the neckline stand out as a design detail.
The sleeve pattern includes cut lines for short sleeves, half sleeves, three-quarter sleeves, and long sleeves, so it can be adjusted for many seasons.
The sewing process is simple, so this pattern is also suitable for everyday wear.
Because the chest opening is deep, please check the fit and coverage while sewing.
After printing, align the pages along the guide lines, paste them together, and cut out the pattern pieces. Seam allowances are included, so you can use the pattern as-is.
*Please press all sewn seams with an iron.
(1) Finish the raw edges along the fold lines at the chest opening of the Front Bodice (Upper) and Front Bodice (Lower). Press the fold lines with an iron, and topstitch.
