The Billie Jumpsuit: The Must-Have Sewing Pattern for Summer! The Billie Jumpsuit offers a subtly sexy and refined look with its front neckline, low back, and a drawstring system that gathers at the lower back, beautifully accentuating the back. It combines this elegance with comfort, featuring wide-leg pants and an adjustable waist. The fully lined bodice allows for wearing without a bra. The Billie Jumpsuit is versatile enough for any occasion, depending on the fabric you choose. Share your makes with the hashtags #poesispatterns & #poesis-billie

FAQ – How to Use My PDF Pattern?
1. How do I download my pattern?
Once you’ve purchased your pattern, head over to your account to download the file. You can download it up to 3 times.
For the best experience, we recommend downloading the file on a computer rather than a phone to avoid compatibility issues. If you’re using an older PC, you may need a program like 7-zip to extract the file. The download should be immediate; if not, please reach out to me at hello(at)poesis-couture.com.
2. How do I print my pattern?
A0 : Take this to a professional print shop.
A4/Letter: Print it at home. Before printing the full set of pages, check the 5 cm test square to ensure the print scale is correct.
3. What are size layers, and how do I use them?
Yes! Seam allowances are included in all Poesis patterns, and they’re set to 1 cm.
On the latest patterns, you may also see the sewing lines. For full details, refer to the instruction booklet.
4. Are seam allowances included?
Les marges de couture sont incluses sur tous les patrons Poesis et sont de 1 cm. Sur les patrons les plus récents, les lignes de coutures peuvent également être affichées. Pour plus de détail, livret d’instructions.
5. What does the projection-optimized pattern file look like?
For newer patterns, we provide a file optimized for projection, which includes a measurement grid in both centimeters and inches.
All pattern pieces are aligned with the grainline, and there’s extra space between them for easier cutting. You’ll find two file options: one with a black background and white lines, and the other with a white background and black lines.
6. Can I sell garments made with your patterns or use them in paid sewing workshops?
Reselling Poesis patterns in any form is not allowed.
However, if you’d like to sell finished garments made with Poesis patterns or use them in paid sewing workshops, there’s a way to do this! Contact me for a Creative License, which gives you permission to use the patterns for commercial purposes. We’ll define the terms together.
