Choosing Your Size

  1. Determine your cup size. You can use the cup size you typically wear.
  2. After determining the cup size, compare your bust circumference (fullest part) to the “Body Measurements” table. Using the corresponding row for your cup, choose the size that best fits your bust. If you are between sizes, choose the smaller size if you like your garment more fitted; otherwise, choose the bigger size.
  3. Compare your waist circumference (narrowest part) to the “Body Measurements” table. Choose the size that best fits your waist. If you are between sizes, choose the smaller size if you like your garment more fitted; otherwise, choose the bigger size.
  4. Compare your hip circumference (widest part) to the “Body Measurements” table. Choose the size that best fits your hips. If you are between sizes, choose the smaller size if you like your garment more fitted; otherwise, choose the bigger size.
  5. It’s OK to use different sizes for the bust, waist and hip. All you have to do is print the sizes that you need, and blend the lines from one size to the next. See “Printing Instructions” and “Blend Sizes” in the instructions.
  6. If you are taller than 5’7” (170 cm) or shorter than 5’4” (163 cm), you should consider lengthening or shortening the bodice (see “Lengthen/Shorten” in the instructions), unless you have long/short torso.

I highly recommend that you check your fit by making a test garment with inexpensive fabrics that have similar weight and stretch as your final garment fabrics.


Primary Fabric Use light to medium-light weight woven fabric with or without stretch. Shirting, broadcloth, lightweight denim, chambray, linen and rayon challis are good choices.

Interfacing Use lightweight woven or weft-insertion interfacing.

Other Materials

  • Five (5) 1/2" (1.25 cm) buttons for the shirt or eight (8) 1/2" (1.25 cm) buttons for the dress
  • Additional two (2) 1/2" (1.25 cm) buttons for the long sleeve option

Fabric Requirements

Most natural fibers shrink in the wash; be sure to have enough fabric. The requirements below assume that the fabric is already pre-shrunk. Due to the width of the pattern pieces, it is not recommended to use 45" (115 cm) wide fabric for sizes 14 to 20.

    This shirt turned out so well! I love that it comes in cup sizes. This is the best fitting button shirt I have had in a long time! I made a second one and I am planning to make the dress.

  2. Jenny (verified owner)

    Great pattern! Instructions very good!

  3. Jean (verified owner)

    This was my first time downloading a PDF pattern. It was easier than I thought and the instructions are very understandable.

  4. Anonymous (verified owner)

    Love the pattern! As a beginner found it to be very clear. The tutorials on the collar were also very helpful.

  5. Julie (verified owner)

    Great pattern, clear detailed instructions.

  6. melodie.kunegel (verified owner)

    I’m amazed by the fit and details of this pattern: simple and perfect. I just added small back darts for a little more waist shape.

  7. Carol (verified owner)

    Apart from the collar (I ended up scrapping my first one and recut another) which I found was extremely fiddley, the pattern went together exceptionally well, far better than many other Indie pattern makers! Unfortunately I don’t have a suitable buttons in my collection so until lockdown ends and I feel safe to go out to buy some, my shirt is unwearable! However, the fit is spot on and a delight to finally not need to do an FBA. As I am so happy with the shirt, I am about to cut a Bonn Dress to sew over the next few days and once again don’t have suitable buttons!

  8. Belinda Renken (verified owner)

    Fits perfect!

  9. Helena (verified owner)

    simple but classic, will be used more than once

  10. Toni (verified owner)

    Very well drafted, fitted without any adjustments. Looking forward to making many more.

  11. Sandra (verified owner)

    I love this shirt. I used a different method for attaching the collar. I attached the upper collar first, then I added the under collar. This ensures, without fail, that the ends of the shirt opening are caught securely.

  12. Virginia (verified owner)

    The extended cup size is great. Yeah!

  13. Marissa (verified owner)

    These instructions / patterns are SO clear and easy to follow! I have never attempted making clothing before, and the short-sleeved shirt I made came out beautifully – I feel so much more confident in making clothing in the future thanks to this fantastically-drafted pattern. I can’t wait to start more projects! 🙂

  14. Julie (verified owner)

    I cut the 0 size with DD bust for my #2 muslin, and adjusted the length, much shorter. Wow, it fits so great, this is an impossible size to find in a store, even in petites. I’m halfway through the first shirt and very much looking forward to wearing it!

  15. Joan (verified owner)

    All your patterns have been great.

  16. Leigh (verified owner)

    Lovely pattern

  17. Lana (verified owner)

    Love this pattern. Such a classic. Love the multiple bust sizes on your patterns. No FBA on most of them them. Yesssss. Got my eye on purchasing at least 3 more patterns to add to the three I have already in my stash. Been watching one of your testers on UTube. She’s from Brazil and gives fabulous tips and ideas. Shame about the low Aussie dollar at the moment but will keep buying anyway. Still very good value in my opinion compared to commercial patterns.

  18. Ruth (verified owner)

    This pattern is really well drafted and the instructions are very clear. I am so pleased to have discovered Itch to Stitch patterns and will definitely be buying more.

  19. Raquel (verified owner)

    Happy with this pattern! I made a dress with this collar and was pleased with the results. Nice clear instructions.

  20. Rosa (verified owner)

    Easy to follow the instructions and with all the cup sizes included, I sewed up the short sleeved shirt in a jiffy! the result is very good! I will soon be making the dress.

  21. Christina (verified owner)

    Great fit and love the pattern based on bust size.

  22. Kimberly (verified owner)

    Love this pattern! I love that it is sized by the high bust measurement and then sized by cup size. The instructions are clear and well-written. I will definitely look forward to sewing another Itch-to-stitch pattern!!

  23. Anonymous (verified owner)

    very slightly smaller than my size range so had to grade up but liked the collar detail. I’d prefer a more fitted version as this style is free of back darts

  24. jackie.rosenberger (verified owner)

    I LOVE this pattern! I’d almost given up on finding a woven shirt pattern to fit me without extensive modifications. Bless you for including A-cup sizing! It is *not* the same as a B regardless of what the Big 4 pattern companies seem to think. The instructions were easy to follow and the pattern was very well drafted. The only change I made was to add 1.5″ to the length (a standard adjustment for me as I am tall). I’ve never had a pattern fit me so well before!

  25. Karyn (verified owner)

    I loved the Bonn shirt. It fits so nicely and I will be making it again. Thank you!

  26. kate (verified owner)

    This is such a good pattern! Both the pattern itself and the instructions were so clear and easy to use. I have made one shirt and now I’;m keen to make several more!

  27. Dayna (verified owner)

    Great shirt. Will enjoy wearing it.
