Fit guide

 Your pattern size isn't your shop size 

Shop sizes vary from brand to brand, so the size on your favourite jeans won't tell you much here. Sewing patterns are sized by body measurements, so grab a tape measure and go by your numbers, not the label you're used to. And remember, the best way to get a fit you love before you cut into your good fabric is to sew a quick test version (sometimes called a toile or a muslin) in cheap fabric first.

How to choose which size to make

Step 1: Measure yourself

Wear light clothing or underwear, and keep the tape snug but not tight. Take these measurements:

  1. High bust: around your body above the fullest part of your bust, under your arms and across your upper back.
  2. Full bust: around the fullest part of your bust, keeping the tape level across your back.
  3. Waist: around your natural waistline, usually the narrowest part of your torso.
  4. Full hip: around the fullest part of your hips and bottom.
  5. Height: standing straight without shoes.

Step 2: Find your size range 

Every Unbound pattern comes in sizes 6 to 38, across two size ranges:

  • B cup range, sizes 6 to 20: drafted for a 5 cm (2 in) difference between high bust and full bust.
  • D cup range, sizes 12 to 38: drafted for a 10 cm (4 in) difference between high bust and full bust.

Sizes 12 to 20 come in both, so you can choose the cup that suits you. This is a sewing cup size, not your bra size, so don't worry if the letter doesn't match what you buy in the shops.

Step 3: Choose your size 

Tops and dresses: start with your high bust measurement, then choose the size with the closest full bust measurement.

  • Depending on your measurements, you may want to do a full bust or small bust adjustment.
  • Between cup sizes? Check the finished garment measurements and choose based on how much ease you like and the style of the garment.

Pants, shorts and skirts: choose by your hip measurement, then check the waist.

Sizing FAQs

What if I'm between sizes?

Bodies rarely match one row of a size chart, and that's completely normal. You can grade between sizes at the waist and hip, for example a 14 at the waist grading out to a 16 at the hip. Each pattern explains how.

What's the difference between body measurements and finished garment measurements?

The size chart shows body measurements. Each pattern also lists its finished garment measurements, which include ease: the extra room that lets you move and gives the garment its shape. Check the finished measurements on the pattern page to see how relaxed or fitted it will be.

What height are Unbound Patterns drafted for?

Unbound Patterns are drafted for a height of 167 cm (5 ft 6 in). If you're taller or shorter, use the lengthen and shorten lines on the pattern pieces to adjust the length.

How can I be sure I've chosen the right size to make?

If you're trying a new pattern or adjusting the fit, sew a quick test version in cheap fabric first. It's the easiest way to get a fit you love before you cut into your good fabric.
