Patternmaking
• Patternmaking - interpretation of garment concept from either a sketch or another existing product, into a paper representation or model for use in production of finished garment style
• Capabilities for projected product style must match original garment concept, yet also meet target customer expectations

Methods of Pattern Development
• Flat Pattern—involves making styling changes to basic two-dimensional pattern – Sloper—five piece pattern of previously
developed and perfected basic body blocks – Select previously perfected final pattern or
body similar to new style – First pattern version usually made up in fabric
as first sample

Pattern Drafting • Begins from scratch for each garment
style • First body measurements taken • Style lines and ease added, resulting in
two-dimensional paper pattern • Done by hand or digitally • More time-consuming and costly; used by
higher-priced, fashion-forward producers

Reverse Engineering
• Pattern made either by transferring measurements of another garment to paper or taking apart existing garment and tracing or digitizing outline of pieces
• Cost-effective for production of basic garments

Draping • Fabric draped or shaped around body
form to create three-dimensional garment prototype
• Once fabric pattern is established, shaped fabric is flattened and its outline transferred to paper or digitized to create two-dimensional pattern blocks
• Used for higher price points, especially with unique silhouettes

New Technologies
• Cutting edge - draping styles directly on computer; elusive due to nature of body movements and variations in textile properties
• Body scan technology - enables retrieval of three-dimensional body measurements from consumer, applied digitally to produce customized product

Patternmaking Needs
• Design-Driven Product Development – Integrity of design more important than
production efficiency – Willing to deal with more complex patterns and
construction – Fabrics less standard, markers vary in
efficiency, specialized sewing capabilities, smaller quantities
– Offshore contractors – May make in-house for accuracy and fit

Patternmaking Needs
• Manufacturing-Driven Product Development – “Commoditize” style by lowering level of
detail, uniqueness, or fit – Simplify construction techniques – Patterns made easy to sew to produce as
many finished garments at lowest possible price in timely manner

Sourcing Patternmaking
• Many advantages of In-house patternmaking within the firm – Fit - experience with target market allows
accommodations to meet customer expectations; market proximity allows for frequent fittings
– Rely on computerized systems to provide greater accuracy, pattern storage, grading, and customized dress forms

Patternmaking Services
• Viable options for those without resources to hire own patternmakers (small start-up companies)
• Computerized system gives accuracy and efficiency without investment
• Located regionally so corrections made quickly and efficiently
• Maintain files of previous work

Full-Service Contractors
• Assume all responsibility for patternmaking, allowing developers to concentrate on their own core competencies
• May be sacrificing consistency, fit, construction details across the brand
• Common in Asia; Central and South America, Caribbean looking to compete

Additional Considerations
• Patternmakers trained in different parts of world use different methods, different perceptions of body and proportions
• Time required to check samples • Lack of familiarity with English measurements • Problem-solving and communication skills
important while working against the clock • Possible duplication of effort

Standards
• Firm’s strategic plan provides foundation for standards that define the business
• Standards - characteristics used as the basis of judgments made about products
• Established to reflect two major goals: – Enable company to make a profit – Meet target customer’s expectations

Chapter 9: Translating Concept to Product

Standards
• Framework for decision in development of product specifications
• Understand firm’s specific standards for product sizing and fit, intrinsic quality standards that provide baseline for consistency of product, and performance standards for materials and finished product
• Focus employee efforts

Standards
• Decided within the firm: styling requirements, construction methods, and measurements for samples
• Imposed by outside agencies – FTC specific care, fiber identification labels – CPSC flammability standards for children’s
sleepwear • If doing business outside United States,
standards such as metric measurements

Specifications
• Specifications (specs) - graphic representations and written descriptions of styling, materials, dimensions, production procedures, and finishing instructions
• Basis for communication with everyone involved in product development chain
• Product developers must write and notate specs to be understood by sourcing partners

Specifications
• Open specs - information provided is generic and contains only very basic facts; allows flexibility for producer or contractor
• Closed specs - require exact materials or predetermine exact supplier; ensure consistency, but can increase end cost of product

Specifications
• Tolerances - variation from identified criteria allowed during production; determine which products will be accepted for sale as first-quality products and which will be rejected
• Products that do not fit within tolerances designated as seconds or irregulars
• Legal and financial bargaining tools

Specification Development
• Phase 1a: Design Specs, prototype specs, preliminary specs, or pre-adoption specs; focus: design, first samples – Based on line plan summary and initial
prototype garments for specific styles – Include style summary sheet with drawing of
the front and back, and preliminary cost sheet with product cost estimates

Specification Development
• Phase 1b: Costing – Preliminary cost sheet - completed with the
first sample • Introductory record of style used to establish
cost of materials, labor, and other costs for production and distribution
• Helps estimate wholesale price charged by wholesaler when garment is sold to retailer or distributor

Specification Development
– Phase 1b: Costing (continued) • General style information repeated from
original style summary sheet • Fabric identification, including price and
quantity of yardage estimates • Listing of trimmings or findings with their
quantity and cost estimates • Estimate of labor costs for producing garment • Wholesale price and markup estimated

Specification Development
• Phase 2: Technical Specs – Called technical specs, style specifications,
or the design spec package – Occurs after a style is adopted and requires
decisions as to how it will be produced – Focus on development of first production
sample and sales samples

Specification Development
• Phase 2: Technical Specs; all information needed for style to be readied for production – Component Spec Sheet – Pattern Chart – Drawing of pattern pieces, with linings and
underlinings (interfacings) color coded – Sewing guides, marker diagram – Size chart

Specification Development
• Phase 3: Production Specs or engineering specs for producing quantities of a product, rather than individual prototype garments
• Emphasis on developing specs early in development process to secure production contracts
• Operations list - identifies each step of construction to determine actual costs

Type of Spec Forms
• Forms in spec package vary by product and firm
• Need documentation for three phases: – Prototype costing – Sample – Production
• Many computer firms specialize in product spec sheet software
