Sewing Notes

Here are some tips we recommend for a successful sewing project:

Fit and style
  • Start by choosing a size with your bust. Refer to the body measurements chart. Then, if needed, you may want to widen or narrow the pattern at the hips if your hips correspond to another size. However, be sure to check the finished garment measurements, because this shirt is not closely fitted, but should also not feel oversized.
  • On the finished garment measurements chart, you can also check the length of the garment and see if it’s suitable for your height. You may want to compare the length with a similar piece of clothing. This had a curved hemline and the length should be long enough to tuck it into a pair of pants.
  • If you need to shorten or lengthen the garment to achieve this look, slash the pattern above the hemline. Slash perpendicularly to the grainline, and spread to add length, or overlap to shorten. When you spread the pattern, fill in the gap with scraps of paper. Tape everything back in place. Be sure to do this on the pattern pieces of both the outer layer and lining.
  • If you adjust the pattern, be sure to replace the button and buttonhole symbols so that they are evenly spaced.
  • Adjust also the length of the sleeve by the same amount you added or removed on the body.
Fabrics
  • For a crisp shirt, pick a lightweight shirting fabric with some stiffness. I recommend sticking to natural fibers such as cotton or linen. You can also add texture to the shirt with an eyelet cotton or embroidered fabric.
  • This pattern is not designed for stretch fabrics.
Cutting out
  • Preshrink the fabric before you start cutting it out. To do so, wash and dry the same way you would with the finished garment. This means you should also take into account the fabric type and its content.
  • Once the fabric is washed and dried, press it to remove all the creases. Be sure that you’ve set your iron to a temperature that is suitable to the fabric. As a rule of thumb, synthetic fibers (acrylic, spandex, polyester…) should be pressed at low heat, and natural fibers (cotton, wool, linen…) should be pressed at high heat.
  • When you’re ready to cut into the fabric, fold it lengthwise, right sides together. The fold should not twist and lay flat. If it’s twisting, unfold and fold again, until it lays flat. Then, place the pattern pieces so that the grainline is parallel to the selvages.
  • Be sure that you don’t cut the notches too much, they should be about 0.3-0.4 cm long (1/8″). If your fabric frays a lot, you may prefer to mark your notches with a chalk.
Sewing
  • This project is intermediate level, making it an excellent choice for those looking to develop their sewing skills further.
  • If you’re not sure how to sew buttonholes, be sure to check your sewing machine manual. The process will vary from one machine to another.

Good luck with your sewing project!

    I made this once already and it is simply perfect, so beautifully drafted, flattering on bigger breasts, too. I’m planning on making another one, do you believe this could work as a sleeveless blouse by removing the sleeves and finishing the armhole with bias tape? Thank you again for sharing!

      Yes of course, but I would probably raise the armhole/side seam corner a bit just in case!
