Ready to level up your sewing skills? If you’ve mastered the basics and want to sew a beautifully constructed shirt or shirt dress, Rosa is a satisfying project that blends classic shirtmaking techniques with wearable, everyday style.
Designed with shaping and structure in mind, Rosa features princess seams, a distinctive pointed yoke, and thoughtful finishing details that give your handmade garment a professional look – inside and out.
Make it as a semi-fitted shirt to wear with jeans, or sew the shirt dress version for an effortless wardrobe staple you’ll reach for again and again.


Why you’ll love the Rosa sewing pattern
Rosa combines timeless design with satisfying construction techniques. It’s ideal for confident beginners and intermediate sewists who want to build their skills while making something truly wearable.
Here’s what makes it special:
- Princess seams on the front and back for gentle shaping

What fabric should you use for Rosa?

- Cotton lawn or shirting
- Chambray
- Lightweight denim
- Linen and linen blends
- Double gauze
- Viscose (rayon) and blends
- Fine needlecord
For a classic shirt dress, try denim with contrast topstitching. For a softer, more fluid look, choose viscose or lightweight lawn. The design details really shine when you play with texture, colour and contrast.
You’ll also need matching thread, buttons for the front opening, and lightweight fusible interfacing for stabilising the collar and facing.
