Official time estimate
Free Lives stated that Dressmaker contains approximately 35 hours of story commissions. Your total will vary with planning, experimentation and how often you redesign or retry a garment.
What the estimate excludes
The estimate does not include off-the-rack creative work. Time spent exploring more than 150 dress pieces, 450 fabrics and 350 accessories can extend play well beyond the story route.
Campaign structure
Steam achievement descriptions confirm major-commission campaigns for ten named clients. Other achievements refer to commissions received by pigeon and several named campaign milestones. This supports a broad campaign structure, but it does not establish an official numbered chapter count.
After major commissions
The official sources support continued creative dressmaking and completion goals. They do not provide a single “post-game ends here” statement, so this guide avoids promising a specific final-state feature that has not been documented.
