Core Responsibilities

Primary Functions

Construct and assemble garments from patterns and technical specifications using industrial and domestic sewing machines (lockstitch, overlock/serger, coverstitch), ensuring seams, finishes, and structural details meet design requirements and production standards.
Perform complex alterations and fittings for clients, including resizing, taking precise measurements, adjusting darts and hemlines, and ensuring proper balance and silhouette to achieve professional fit for bespoke and ready-to-wear garments.
Read, interpret, and act on tech packs, graded patterns, line sheets, and alteration notes from designers or fit technicians, translating written specifications into accurate sewing operations and finished garments.
Create samples and prototypes for new styles, collaborating with designers and pattern makers to identify fit issues, recommend construction adjustments, and suggest fabric or trim substitutions to meet aesthetic and functional goals.
Operate specialty machinery (buttonholers, bar tackers, blind stitch machines, binding machines, fusing presses) and perform set-ups for specific operations such as sleeve-insertion, collar construction, and pocket application to maintain consistent quality.
Execute precise hand-sewing techniques (pick-stitching, slip-stitching, appliqué, beading, and couture finishes) for high-end garments, bridal wear, or delicate fabrics where machine work is unsuitable.
Cut fabric panels from markers or patterns with accuracy, including working with nap, pattern matching, and directional prints to minimize waste and ensure visual alignment across seams.
Perform pressing and finishing operations to enhance garment appearance and longevity, including steaming, pressing seams, shaping collars and cuffs, and applying final trims and labels prior to packaging.
Inspect garments at multiple production stages to identify and correct defects (skewed seams, puckering, skipped stitches, incorrect trims) and document quality issues to reduce rework and maintain compliance with company standards.
Maintain productivity targets and track individual production metrics (pieces per hour, cycle time) while complying with quality metrics, escalating bottlenecks or equipment issues to supervisors for resolution.
Manage custom order workflows from intake to delivery, recording client specifications, communicating timeline expectations, and coordinating fittings to ensure timely completion of bespoke and alteration projects.
Advise clients and customers on fabric selection, care instructions, alteration feasibility, and cost estimates for custom work, building trust and ensuring a positive customer experience in retail and atelier settings.
Collaborate with the production planning team to sequence work, prioritize rush orders, and balance sample room and production demands, ensuring deadlines for seasonal collections and deliveries are met.
Maintain workshop organization and inventory of consumables (threads, needles, interfacing, buttons, zippers) and report supply needs to purchasing to avoid work stoppages and to manage cost control.
Train and mentor junior seamstresses, apprentices, and cross-trained employees on machine operation, standard sewing procedures, quality standards, and safety protocols to maintain a skilled workforce.
Adapt construction techniques to a wide variety of fabrics (silk, chiffon, denim, leather, knits, technical synthetics) and trims, selecting appropriate needles, thread types, stitch lengths, and tension settings to prevent damage and ensure workmanship.
Document alterations, modifications, and sample corrections in the production log or PLM system, ensuring traceability and that corrective actions are captured for future runs.
Perform basic machine maintenance and troubleshooting, including changing needles, adjusting tension, oiling equipment, and coordinating preventative maintenance with equipment technicians to minimize downtime.
Implement safety and housekeeping standards in the sewing area, ensuring compliance with regulatory and company policies for ergonomics, machine guarding, and fire/safety protocols.
Produce couture-level finishing and handwork for high-value garments, such as boning insertion, pad stitching, hand-sewn hems, and internal structure assembly required for bridal and tailored coats.
Provide accurate time and labor estimates for alterations and custom commissions, inputting quotes and turnaround times into the point-of-sale or production scheduling system.
Participate in fit sessions with designers and fit models, providing technical feedback on construction methods and suggesting modifications to improve fit, drape, and movement.
Assist with pattern alterations and minor grading tasks, making on-the-fly pattern corrections and marking patterns for sample rework to expedite production cycles.
Manage returns, repairs, and warranty alterations by diagnosing wear or failure points and applying appropriate repair methods that restore the garment to acceptable condition.
Maintain confidentiality and discretion when working on high-profile or bespoke client projects, handling sensitive fittings and client measurements professionally.

Secondary Functions

Support showroom or retail staff during peak periods by performing express alterations and providing quick turnaround repairs to maintain customer satisfaction.
Contribute to continuous improvement initiatives by suggesting process improvements, time-saving techniques, and quality checks that reduce defects and increase throughput.
Assist designers and technical designers with fabric testing, seam allowance trials, and choice of construction methods for small-batch or sample orders.
Coordinate with external vendors (embroidery houses, dry cleaners, pressing services) to ensure outsourced operations meet quality and timing expectations.
Maintain digital records of sample iterations, fit notes, and approved changes in the company’s PLM or shared drive to preserve institutional knowledge and speed up future runs.
Participate in training sessions on new machines, sustainable materials, or updated compliance standards to stay current with industry best practices.
Help prepare costings and bill of materials for bespoke pieces by recording exact trim usage and labor hours associated with complex garments.
Assist in merchandising by preparing garments for display, ensuring samples are finished to showroom quality and represent brand standards.
Provide ad-hoc support for event dressing, costume changes, or emergency repairs for photoshoots and live events.
Mentor interns and vocational students on workplace expectations, basic sewing skills, and career pathways in tailoring and garment construction.
