Reminder that seam allowances are 1 cm wide, unless stated otherwise.
- Sew the shoulders.
- Cut elastic #2 in two and gather the collar with the elastics between the markings.
- Make the neckband.
- Attach the neckband to the neckline. The band needs to be stretched to fit.
- Sew the front and back at the side seams.
- Add stay tape at the crotch opening edges (wrong side of fabric).
- Apply a clear elastic on each leg opening (wrong side of fabric). The elastics also need to be stretched to fit.

- Hem the crotch openings with the single needle (turn once 1 cm).
- Add the snaps on the crotch openings. The front should overlap the back.

This pattern was so easy to make and it came out so good! It’s also easy to alter to your liking. I changed it up a bit and chopped off the bottom so it’s just a shirt. The sizing guide is actuate as well. I always have to make sizing alterations on other patterns but not on this one.
Lo hice hace unos dรญas y quedรณ esplรฉndido! Los talles son acertados!! Muchas gracias por compartirnos tus conocimientos ๐ค
Haii, i need some help with following the instructions. I donโt understand how the elastics are needed? especially in collar part. please help :((
Hello, the elastics are for gathering the collar and adding stability to the leg openings. You can find videos on YouTube on how to gather using clear elastics.
