When you sew plus size, the real problem isn't the sewing: it's finding plus-size sewing patterns that actually come in your size, then adjusting them to your proportions. The way through: find a pattern whose grading reaches your size (many stop at a French size 46), choose your size on the area that is hardest to alter, then make the two or three adjustments that really matter: bust, hips, tummy and front length. The techniques are the same as for any sewist; what's missing is the patterns.
In short: when the sizes stop where yours begins, you are not "outside the norm": the size chart is simply too short. A size chart describes a statistically average body, and it freezes its proportions: it assumes a full bust goes with particular hips, which no real body respects. The answer is not to adapt yourself to the template, but to start from your measurements.
Why is it so hard to find plus-size sewing patterns?
Because most patterns are graded over a limited range, often up to a French 44 or 46, from a single "reference body". Beyond that, the pattern company would have to rework the grading (the regular step between two sizes), because body proportions don't grow in a straight line: past a certain frame, it is mostly the bust, tummy and hips that gain fullness, not the shoulders or the neck. Rather than do that work, many brands simply stop, and the curvy sewist hits a wall.
The result: grading a pattern up yourself beyond its largest size ("home grading") quickly distorts armholes, necklines and curves, because you add the same amount everywhere. It can be done, but it is pattern cutting work, not a shortcut.

Create a pattern to my measurementsHow do I choose a pattern as a curvy sewist?
Three habits avoid disappointment, before you even buy the fabric:
- Check the pattern's size range (not just the picture): your bust and hip measurements must actually appear on it, not be "extrapolated".
- Read the chart measurement by measurement, never as a whole. Since our measurements often fall on several rows, choose the size on the area that is hard to alter: the bust and shoulders for a top, the hips for a bottom (how to read a size chart).
- Favour forgiving cuts for a first project: elasticated waist, empire line, fluid lines, gathers. They tolerate small differences better than a very fitted cut.
Here is a guide to help you match French sizes to body measurements. Every pattern company has its own chart, so always trust the one on your pattern:
| Size (French numbering) | Indicative bust | Indicative hip | Commonly available? |
|---|---|---|---|
| 44 | 104 cm | 112 cm | Common |
| 46 | 108 cm | 116 cm | Common (often the upper limit) |
| 48 | 112 cm | 120 cm | Less common |
| 50 | 116 cm | 124 cm | Rare |
| 52 | 120 cm | 128 cm | Rare |
Reading the table: around a French 46, many patterns stop. For a larger size, either look for a pattern company whose chart genuinely goes that far, or start directly from your own measurements.
Which fitting adjustments really matter for a curvy figure?
There's no need to alter everything: three areas account for most of it. For the detail of each technique, our guide to adapting a pattern to your body shape goes through every adjustment step by step.
- The bust: a full bust adjustment (FBA) is almost always useful, because the cup difference increases with the figure. You widen the front only, without touching the shoulders (the FBA step by step).
- The tummy and front length: a rounded tummy "uses up" length: the front rides up and the hem flares away. Lengthen the front and add a little ease over the tummy, without tightening the waist.
- The hips and grading between sizes: when bust and hips fall on different sizes, join the two lines with a gradual blend along the side seam rather than settling on a single size.
Do curvy sewists need more ease?
Not necessarily "more": ease in the right place. The classic mistake is to enlarge everything "to be comfortable", which gives a garment that floats at the shoulders and pulls across the tummy. Keep standard wearing ease at the bust and hips, and add it where the body needs it (the tummy, the upper arms) without drowning your shape. Comfort comes from the right amount, not the maximum.
As we put it in the studio: "A curvy sewist doesn't need a bigger pattern: she needs a pattern in her proportions. A pattern company's size 50 isn't your body made larger, it's their reference figure stretched. Made-to-measure begins exactly where the size chart stops."
That is precisely the lock our online pattern studio opens. Instead of hunting for a pattern that "goes up far enough" and then pushing it beyond its chart, you start from an inspiration photo and your measurements, and receive a pattern drafted to your body measurements (a dress to your measurements, for example) with no size chart to choose from, bust and front length included, up to a 150 cm bust and 160 cm hips. No template that doesn't exist in the shops: your body is the size chart.
Frequently asked questions about plus-size sewing
How far up do sewing pattern sizes go?
Many patterns stop at a French 44 or 46. Some pattern companies go higher, but availability drops sharply beyond that. Always check the pattern's actual size range before you buy it, not just the photo of the garment.
Can I grade up a pattern that is too small myself?
You can, but it isn't a simple "+2 cm everywhere": past a certain size, grading is no longer linear and enlarging distorts armholes and necklines. For an accurate result, you are better off with a pattern already graded to your size, or drafted to your measurements.
Which size should I choose for a top when I'm between two?
The bust and shoulders decide: choose the size for those areas, which are hard to alter, then adjust the waist and hips further down by grading between sizes. It is much easier to take fabric away than to add it.
Which fabrics work best for plus-size sewing?
Fabrics that are both soft and have good body: viscose, light twill, stable knits. They follow movement without showing every strain, whereas a very stiff fabric highlights the tension points and an overly fluid one clings to curves.
Do I always need a full bust adjustment?
Very often, yes. The difference between full bust and high bust tends to increase with the figure, which goes beyond the reference cup size of most patterns. A full bust adjustment widens the front without touching the shoulders or the neckline.
Plus-size sewing shouldn't be a hunt for a pattern that doesn't exist. Start from a photo of a garment you love and your measurements, and let our online pattern studio draft a pattern to your body (no size chart to choose from, with its sewing instructions), checked before it is sent. Finally sew to my measurements.
