Where sewing sits
Sewing in the Dressmaking Flow
Assembly prepares the garment pieces. Sewing is where those pieces are actually joined — and it is the stage the game scores.
- Cut
- Assemble
- Sew — You are here
- Decorate
- Finish
The stage that is scored
Cutting decides how the panels were placed, and assembly decides where each piece belongs, but neither of them adds a number to the finished garment. Sewing is different: every join it makes feeds Sewing Accuracy, and Sewing Accuracy is one of the three inputs the game weighs into Quality. A dress can be cut cleanly, aligned on the grain and assembled without a single missing piece, and still finish poorly if the sewing was rushed.
The catalogue publishes 178 patterns, 236 construction variants and 1,871 panels between them. Every one of those panels has to be joined by hand before the dress is finished.
Before you sew
What has to be true before the first join
Sewing is the last stage of making, so it inherits every mistake made before it. If any line below is false, the fault is upstream and the sewing step cannot fix it.
- The Pattern is the one the design needs
- The Variant is the one you selected
- Every panel that Variant cuts has been cut
- Every piece is placed on the mannequin, in its garment part
- Each piece carries the Fabric you chose for it
A missing piece is not a sewing problem
A join cannot be sewn to a piece that was never cut. When the mannequin is short of a piece, the answer is in the cutting room, not in the sewing step — and no amount of care at the needle will move the score.
Step 1 — the garment
Sew the garment the design actually has
Sewing follows the mannequin: the bodice, the skirt, and the sleeves and collar if the design has them. The pieces belonging to each part were decided long before the needle.
The four parts the catalogue is built from are the four the mannequin shows. A design with no sleeves has no sleeve piece to sew, and nothing is left unfinished by that — a part the design never used is not a seam the game is waiting for.
| Garment part | Patterns in the catalogue | In a dress |
|---|---|---|
| 身頃 | 67 | Every dress has one |
| スカート | 56 | Every dress has one |
| 袖 | 34 | Only when the design has it |
| 襟 | 21 | Only when the design has it |
Those counts are patterns in the catalogue, not pieces in your dress. The pieces your dress needs are the ones the variant you selected cuts, and the assembly guide is where they are grouped.
Step 2 — the interaction
Follow the sewing sequence the game shows
Sewing is a hands-on stage. The game presents one piece against the piece it neighbours, you line it up, and you sew that join before moving on.
The whole garment is never on the table at once. Each join is its own small task — take the piece as it is offered, match it to its neighbour, and sew. That is also why the stage can be finished out of any order the game offers: the sequence is the game's, not this page's.

No published order of seams
The game publishes the join, the rotation and the sew action. It does not publish a fixed front-then-side-then-back order, and this page will not invent one: take the joins in the order the game offers them, and finish each one before moving to the next.
Step 3 — the score
What Sewing Accuracy is
Sewing Accuracy is how accurately the garment was sewn during construction. It is not a pass-or-fail check that the seams were made — it is a score, and it is the heaviest single input to Quality.
Two of Quality's three inputs are printed on screen while the dress is being made: grain placement in the cutting room, and the fit on the mannequin. The third is settled here, at the needle, which is what makes sewing the last place a player can still change the finished score.
Where each input is decided
Grain
In the cutting room, printed as Grain Quality — how well the panels were laid to the grain.
Fit
On the mannequin, printed as Mannequin accuracy — how closely the sizing matched the client.
Sewing Accuracy
During sewing. Sewing is the stage this site calls Sewing Accuracy, and the game's own line for finishing it is Sewing Complete!
Sewing Accuracy is not Quality
Sewing Accuracy 85 does not make the dress Quality 85. The three inputs are combined with their own weights, so the other two still have their say — and a dress placed badly on the cloth or sized badly on the mannequin will not reach the score its sewing deserved.
This page publishes the weight Sewing Accuracy carries, not a per-join formula. The build records the sewing interaction and the quality formula's shape, not how the game turns one join into a number, so nothing here guesses at it.
How the score is built
How Sewing Accuracy Affects Quality
Quality is a weighted sum of three inputs. Sewing Accuracy is the largest of them, and the one decided last.
- Grain30%
- Fit20%
- Sewing Accuracy50%
Quality from its three weighted inputs: Grain 30%, Fit 20% and Sewing Accuracy 50%.
These are the recovered weights, and they are the same ones the sale price calculator on this site uses — the rows above and the numbers that tool produces come from one place.
Two branches
Sewing with and without Measurements
Which inputs exist depends on whether the dress was made to a client's measurements, and that decides how much of Quality sewing owns.
With measurements
- Grain30%
- Fit20%
- Sewing Accuracy50%
All three inputs are in play, and sewing is half of the score. This is the branch where a dress that was fitted and aligned beautifully can still finish badly, because the needle is holding half the marks.
Without measurements
- Grain40%
- Sewing Accuracy60%
Fit is dropped from the sum entirely rather than scored as zero, and the other two are re-weighted to carry the whole score. Sewing Accuracy becomes the majority of it.
The consequence is worth stating plainly: on an off-the-rack dress, sewing is the biggest single thing a player controls about Quality.
Controls and settings
The Sewing Controls and Sewing Assist
Sewing is the one stage of making with its own on-screen controls, and the game ships a setting that sits beside them.
On-screen controls
The hints shown during the stage name three actions: rotate the piece, change speed, and sew. Nothing else is needed to finish a join — the piece is already matched to its neighbour when it is offered.
Sewing Assist
The game's options menu carries a setting named Sewing Assist. It is the first place to look when the sewing step itself is what keeps going wrong — but the build this site is generated from records the setting and not its effect, so no page here claims what it changes.
Thread colour, added in Build 410
Sewing here is a join between two pieces rather than a threaded machine to be set up, so for most of the game's life there was no thread colour to change. Build 410 added one: a click on a spool in the sewing scene. The build this site's data is generated from predates it, so nothing else on this page depends on the interaction — the recovered data records the rotation, the sew action and the assist setting.

Common Sewing problems
Five ways this stage goes wrong, and which page owns each one.
- The dress will not finish sewingA join you cannot reach, or a dress that stays unfinished after you have sewn everything you can see, is a known situation rather than a broken dress. It has a specific answer rather than being a reason to start over.Finish the other side
- The next join never appearsCheck the part you are on, whether every piece that part needs is on the mannequin, and whether the assembly was finished. A piece still sitting in the inventory cannot be sewn, and the game will not offer a join it cannot make.See how pieces are grouped
- Sewing is finished and Quality is lowSewing is one of three inputs. Before blaming the needle, check how the panels were placed in the cutting room and how closely the mannequin matched the client — either of them can hold a score down on its own.Understand Quality
- The fit was perfect and Quality is notA perfect fit guarantees Fit's share of the score and nothing more. Grain and Sewing Accuracy carry the rest, and neither of them follows from the mannequin being right.
- The dress looks right and Quality is lowHow a dress looks and how it was constructed are separate answers. Style is what the design and the materials declare; Quality is what the cutting, the measurements and the sewing actually did.
Keep the systems apart
Sewing, Style and everything else
Sewing Accuracy moves one number, and it is rarely the number a client's brief asks about.
Sewing
Affects Quality. Careful sewing cannot raise Cute, Formal or any other style score, and rushing it cannot lower them either.
Patterns
Decide the structure of the dress and carry the style tags the design is scored on, whatever the cloth.
Fabrics
Supply the colour, the fabric type, a weighted style contribution and most of the material cost.
Accessories
Meet the count, variety and trim requirements a brief asks for, and contribute to Style and Elaborate.
A dress can be sewn beautifully and still fail a brief it was never designed for. Sewing cannot supply a tag the pattern does not carry.
Before you leave the needle
What to check before the dress is finished
Sewing ends when the garment is complete, and the game says so plainly. Five things are worth confirming before you accept that.
- Every join the mannequin asked for has been sewn
- No garment part is left half finished
- Sewing Accuracy has been read, not assumed
- No side or back is left unreachable
- The sewing settings are the ones you meant to use
The dress is sewn.
Next
Next: decorate the dress
Sewing produces a finished garment; decoration is what most briefs actually ask about. Accessories are placed next, and they are what turns a well-made dress into one that passes.
The dress keeps its Quality when it is decorated. Nothing on the accessory table can raise a score the sewing already cost you.

About this page
Sewing in Dressmaker is the stage between a garment that exists and a garment that is finished. The dress arrives on the mannequin already assembled — bodice, skirt, sleeves and collar placed from the pieces the chosen pattern variant cut — and sewing is the interaction that joins them, one piece to its neighbour, until the garment is complete. What the game scores here is Sewing Accuracy: how accurately the dress was sewn, weighted 50% of Quality when the dress was made to a client's measurements and 60% when it was not, because Fit is dropped from that branch entirely. That makes sewing the heaviest single input to Quality rather than a formality at the end of the process, and it means a perfect fit can still be undone by rushed joins. Sewing Accuracy is not Quality, though: grain placement from the cutting room and the fit captured on the mannequin carry their own shares. Problems here are specific ones — a back that cannot be reached, a piece still in the inventory, a low score on a dress that looks right — and each has its own answer rather than a single fix.
This page covers the sewing stage and the score it produces. The decoration stage that follows, and the full calculation behind Quality, are handled on their own pages.
