Extended sizing is where shirt factories genuinely separate. Scaling a base pattern upward by arithmetic produces the fit failures plus-size customers know on sight: armholes that gape, collars that stand away from the neck, buttons that pull across the chest. A proper extended range starts from a separate block drafted on a fuller figure, with the dart placement, sleeve pitch and button spacing rebalanced rather than enlarged. The Turkish workshops that serve European plus-size specialists maintain those blocks as standing assets, which is exactly what a buyer should ask to see before requesting a price.
The commercial case is strong and still underserved. Plus-size shoppers report fewer credible options and repay brands that fit them with loyalty rates mainstream ranges rarely achieve, while the online plus-size segment keeps outgrowing apparel as a whole. The catch is unit economics: a 4XL shirt consumes meaningfully more fabric than a medium, and honest factories price by consumption tier instead of quoting one flat rate that penalizes either side of the curve.
Listings on this page match shirts offered in extended ranges, typically 2XL through 6XL or UK 18 through 32. When you enquire, state the size span and the ratio across it — factories weight the cutting marker to your curve, and a realistic ratio from your sales history beats any generic assumption they could make.
Plus size shirts: sourcing questions answered
- How much more does a plus size shirt cost to produce?
- Expect a graded uplift rather than a single figure. Fabric consumption rises roughly eight to fifteen percent per size band above 2XL, and cloth is the largest single cost in a shirt, so a 5XL commonly prices ten to twenty percent above the core-size rate depending on the cloth width and how efficiently the marker nests. Labor changes far less — the seams are longer but the operations are identical — and trims barely move at all. Insist on a quote broken out by size tier: factories that offer one blended price across the whole curve are either overcharging your core sizes or planning to recover margin on the extended ones. A tiered quote also lets you set retail prices deliberately, whether you absorb the difference for a single-price policy or step the ticket.
- Do factories draft plus size patterns or do I supply a block?
- Both routes work, and the right one depends on what you already own. If your brand has a proven extended-fit block from previous production, send it with the tech pack and the factory will digitize and grade from it, preserving the fit your customers already accepted. If you are entering plus sizes for the first time, ask the factory to develop from its own house block on a fuller-figure form, then run a real fit session — ideally on a fit model of your target size, not a dress form — before approving the size set. Budget one extra sampling round compared with a core-size program; the second prototype is where armhole and across-back corrections land. A factory that resists fit sessions on extended sizes is telling you it plans to scale mathematically, which is the outcome you are paying to avoid.
- What size range can Turkish shirt factories actually cut?
- Most established shirt plants handle 2XL through 6XL without special tooling, and several go beyond on request. The practical constraints are cloth width and marker efficiency rather than willingness: standard 150 cm shirting nests efficiently up to around a 170 cm chest circumference, beyond which the marker maker either accepts more waste or the factory buys wider cloth, both of which show up in the quote. What matters more is the grading interval — good extended ranges grade in smaller, uneven steps at the top of the curve because bodies do not grow linearly. Ask to see the factory's grade rule table for sizes above 3XL; a thoughtful one is the clearest single signal that the plant has done this work for real customers before, rather than improvising it for your order.
