i.Precision Pattern Engineering

Patterns built for balance, ease and construction logic — they sew cleanly at scale, in every size.

ii.Factory-Ready Documentation

Tech packs and files your manufacturer executes without a single clarification email.

iii.Luxury Sample Development

Fit-first sampling refined until the garment matches the brief — development revisions within the agreed scope are included, not billed as extra.

iv.Worldwide Collaboration

Brands across the globe, one accountable studio — clear scope, clear timelines, in writing.

01 — Selected Work

Recent projects from the atelier.

A selection of development work — patterns, grading, tech packs and 3D sampling delivered to brands and designers worldwide. Client names withheld where confidentiality applies.

02 — Services

Everything a collection needs
before the factory.

One studio, one standard of precision — whether you need a single production pattern or full apparel development of your collection.

i.

Pattern Making

Production-ready patterns engineered for clean fit, efficient sewing and consistent results at scale — from a sketch, photo or sample garment.

ii.

Pattern Grading

Accurate, size-chart-driven grading across full size ranges, including inclusive and extended sizing, with fit integrity preserved in every size.

iii.

Tech Packs

Factory-fluent technical packages: measurements, construction, BOM, colourways and grading rules — clear, factory-ready documentation designed to reduce development questions and production errors.

iv.

Sample Development

Fit-sample coordination and revision management — we prepare sample-ready files, review fit photos or samples, and refine until the fit is approved.

v.

3D Sampling

Photorealistic 3D garment visualisation and virtual fitting — approve silhouette, fit and fabric behaviour before a single physical sample is cut.

vi.

Marker Making

Optimised markers that cut fabric waste and cost — nested for your lay lengths, fabric widths and production quantities.

vii.

Digital Sewing Patterns

Beautifully drafted PDF patterns for designers and home sewists — layered, in A4, US Letter, A0 and projector formats with clear instructions.

viii.

Production Consulting

Manufacturing support from someone who knows the factory floor — costings review, size-set strategy, vendor communication and pre-production problem solving.

03 — Expertise

Every category. One standard.

Apparel development across the full spectrum — from industrial uniforms to couture-level luxury collections.

04 — Delivery Formats

Your factory's language, spoken natively.

Development work is only useful if your manufacturer can open it. Every THELYSH Atelier project can be delivered in the industry-standard CAD formats used by factories and studios worldwide — cleanly layered, annotated and organised, with a complete ZIP project handover so nothing gets lost between design and production.

05 — Process

Quietly rigorous, start to finish.

1

Brief

Share sketches, references or a sample. We define scope, sizes, formats and deadlines — clearly, in writing.

2

Develop

Patterns are drafted and refined with obsessive attention to balance, ease and construction logic.

3

Prove

3D fit review or sample feedback. Revisions within the agreed scope are part of the process, not billed as extra.

4

Deliver

Production-ready files in your factory's CAD format — Gerber, Lectra, Tukatech, DXF or PDF — documented and organised.

06 — The Atelier

Built on craft.
Named for love.

THELYSH Atelier was founded on a simple belief: the difference between a good garment and a beautiful one is decided long before the fabric is cut — in the pattern.

“A pattern is a promise. We make sure it's kept — in every size, every time.”

Our expertise was earned inside Sri Lanka's export apparel industry — one of the world's most demanding manufacturing environments, trusted by global fashion houses. We bring that production discipline to independent brands, with the personal care of an atelier.

i.Industrial pattern engineering across major CAD systems — and the judgment to know when the machine is wrong.
ii.Fit-first development: construction logic, fabric behaviour and grading integrity considered from the first line.
iii.Factory-fluent documentation your manufacturer can execute without a single clarification email.

07 — Questions

Frequently asked.

Quick answers to what brands and designers ask us most.

What's your typical turnaround time?

A typical pattern development is delivered in 2–3 days. Larger scopes — full collections or complex styles — receive a clear timeline agreed with the quote before work begins.

Do you offer revisions?

Development revisions within the agreed scope are included as part of the refinement process — we refine until the fit matches the brief. If the design itself changes direction, we discuss the new scope together and agree pricing before continuing.

How is pricing calculated?

Every project is quoted individually — pricing depends on style complexity, size range and deliverables. You receive a clear quote before any work begins, so there are no surprises.

What CAD formats do you deliver?

Gerber AccuMark (ZIP · MDL), Lectra Modaris, Tukatech, DXF (ASTM & AAMA), PLT plotter files, PDF and AI — with a complete organised ZIP handover on every project.

How does sample development work?

We prepare sample-ready files, review your fit photos or physical samples, and refine the pattern until the fit is approved, with revisions within the agreed scope included as part of the process.

Do you work with new and emerging designers?

Yes — from an independent designer developing a first collection to established international brands, every project receives the same precision and care.
