Launch Day is finally here!
I’m so excited to officially share the Bertie Shirtie with you!
So much time, care, and intention has gone into this pattern—from the drafting to the testing—and I’m incredibly grateful to my testers for helping make Bertie what it is ❤️
The Bertie Shirtie is a relaxed woven t-shirt with a simple drop shoulder and an easy, comfortable fit. It includes:
• 22 sizes
• Short and long sleeve options
• Two cup size options (A/B and C/D)
It’s designed to be approachable, with a few skill-building steps along the way—making it a great project for adventurous beginners and a satisfying, quick sew for more experienced makers. Fabric requirements range from approximately 1.25–2.75 yards, depending on your size and view.
The pattern is drafted for a height of 5’4” (162.6 cm), and instructions for common fit adjustments are included in the tutorial.
A big thank you to for doing this photoshoot with me. I can’t wait to start sharing all of the tester makes—there are so many good ones coming. I’ll be posting a tester appreciation later today!
To celebrate launch, you can use code BERTIE20 for 20% off anything in my Etsy shop through March 28.
Thank you so much for being here and supporting my work! 🤗
