Here’s a riddle for you: what’s ultra-comfy, casual, modern, and about to become your new favourite make?
Answer: Billie.
Billie is a relaxed-fit sweatshirt and sweater dress sewing pattern designed for everyday wear. Whether you’re working from home, heading out for coffee, or spending a slow day at your sewing machine, Billie is one of those makes that feels as good as it looks.
With multiple sleeve options, two length variations, and optional cutaway pockets, Billie is endlessly customisable depending on your fabric choice and style.

Billie sewing pattern design details
Billie is a modern take on the classic sweatshirt, designed with comfort and style in mind.
All versions feature a relaxed (but not oversized) fit, a crew neckline finished with a classic neckband, and a clean, wearable silhouette.
You can choose from multiple style options:
- Top length finishing at the high hip
- Mini dress length finishing approx. 10cm (4in) above the knee
- Straight sleeves in full-length or three-quarter length
- Statement balloon sleeves with deep cuffs
- Optional cutaway pockets for the dress version
- Deep hem band finish for both versions
Billie is designed to feel like “secret pyjamas” — the kind of outfit that looks put-together but feels like loungewear. Comfortable enough for sofa days, but polished enough for going out.
And yes — the dress version has pockets big enough for your phone.

Best fabrics for the Billie sewing pattern
Billie is designed for medium- to heavy-weight knit fabrics with at least 10% stretch.
Great fabric choices include:
- Sweatshirt fleece
- French terry
- Loopback jersey
- Ponte
- Double knit
- Interlock
- Sweater knits
For cuffs, hem bands, and neckband finishes, you’ll ideally want fabric with at least 20% crosswise stretch. If your main fabric is less stretchy, ribbing is a great alternative for a professional finish.
If you’re sewing the balloon sleeve version in thicker fabric, take care when gathering sleeve heads — your machine may need to work a little harder through bulkier seams.
Is the Billie sewing pattern beginner-friendly?
Billie is designed for confident beginners who are ready to start sewing with knits.
If you’ve made a few garments before, you’re good to go. If this is your first time sewing jersey fabrics, Billie is a great place to start — especially if you choose a stable knit like French terry or loopback.
You’ll be guided through techniques including:
- Sewing knit neckbands
- Working with sweatshirt fabrics
- Gathering sleeve heads (balloon sleeve option)
- In-seam pocket construction (dress version)
Everything is explained step-by-step with Tilly and the Buttons’ signature photo instructions.
