Regular T-Shirt: A Core Piece in Custom Apparel Manufacturing

Why the regular t-shirt still leads custom apparel in 2025

The regular t-shirt remains one of the most widely used garments in custom apparel manufacturing. Its universal appeal, low complexity in production, and versatility for printing and branding keep it at the center of many brands’ first collections. In 2025, brands that prioritize sustainability, traceability, and high-quality European production increasingly choose Portugal as their manufacturing partner.

A quick framing: market context and Portugal’s role

Global t-shirt demand continues to grow, driven by customization, sustainability trends, and the rise of direct-to-consumer brands. Portugal’s textile industry strengthened its position by combining competitive European lead times, lower minimums suited to startups, and a strong focus on certified eco-fabric options. For brands that want shorter transit times to the EU and U.K., plus strong quality standards, Portugal offers a compelling balance of reliability and prestige.

Why brands choose regular t-shirts as the foundation of a collection

Regular t-shirts function as both a primary product and as a testbed for experimentation. They are ideal for: establishing brand fit profiles, testing fabric choices like organic cotton or bamboo blends, and validating colorways before moving to higher unit items like hoodies or outerwear. Because production is technically less complex than multi-panel garments, t-shirts are a low-risk, high-value place to start.

Portugal advantages — quality, speed, sustainability

Portugal offers vertically integrated mills and factories which can source, dye, knit, and finish garments under one roof. That verticality reduces quality variance and speeds up sampling. Many Portuguese manufacturers also hold GOTS, OEKO-TEX, and other certifications, making it easier for brands to market sustainably made collections with credible documentation.

Fabric selection: choose the right knit

Fabric choice determines the garment’s hand, drape, durability, and suitability for printing or finishing. Below is guidance to choose fabrics that align to brand positioning and function.

100% cotton — the everyday workhorse

100% cotton offers breathability and printability. It’s the most cost-effective option for bulk and printing blanks. Choose ringspun cotton for a softer hand, and request GSM (grams per square meter) and shrinkage tests. For brands targeting a premium audience, a mid-weight ringspun (160–200 GSM) offers good structure and printing results.

Organic cotton — sustainability without compromise

Organic cotton is now mainstream for conscious brands. Compared to conventional cotton, organic reduces pesticide use and can improve brand storytelling. Portuguese mills that source GOTS-certified organic cotton simplify verification and marketing claims for brands selling in environmentally sensitive markets.

Blends (cotton-poly, bamboo blends)

Blends add durability, stretch recovery, and moisture management. Cotton-poly blends are common for activewear and durable retail blanks. Bamboo blends add softness and natural moisture wicking — ideal for lifestyle and athleisure collections.

Customization methods & how to plan for them

Choosing the right decoration method affects minimums, lead times, and per-unit costs. Below are practical recommendations for each method.

Screen printing — best for bulk runs

Screen printing gives vivid, durable prints at low per-unit cost when ordered in large runs. Use water-based inks for softer hand and eco credentials. Typical add-on costs vary depending on color count and print placement.

Embroidery — premium texture

Embroidery is ideal for small logos or chest marks and creates a premium perception. It adds cost but increases perceived garment value and retail price potential. Portuguese factories often handle embroidery in-house or via trusted local partners.

DTG and sublimation — for complex art

Direct-to-Garment (DTG) supports full-color, photo-quality prints on small runs. Sublimation is best for polyester fabrics and all-over prints. Both offer low MOQ options, but per-unit costs are higher than large-scale screen printing.

Cost, MOQ, and lead time expectations (practical planning)

When planning production, align your unit economics with MOQ realities and lead times. Typical regional comparisons in 2025 help set realistic expectations:

Portugal: MOQs often start at 100–300 units per style, average production lead time 4–8 weeks for bulk orders, and strong on quality control and sustainability documentation. Typical FOB unit costs for cotton t-shirts range from roughly €3.20 to €7.50 depending on fabric and finishing.

Asia (Bangladesh, China): Lower unit costs but higher MOQs (500–1000), longer lead times (10–14 weeks), and longer shipping times to EU markets. If you need speed to market and smaller runs, Portugal is often a better fit even with a higher unit cost.

Practical production checklist for first-time brands

1. Start with swatches: Request swatches with GSM, shrinkage tests, and colorfastness reports.
2. Confirm certifications: Ask for GOTS/OEKO-TEX reports when sustainability is required.
3. Define decoration strategy: Decide which designs need DTG or sublimation and which are screen printed to budget correctly.
4. Negotiate MOQs: Many Portuguese manufacturers will lower MOQs for a small premium or a first order agreement; clarify this early.
5. Create a tech pack: Include flat sketches, measurements, fabric codes, and fit notes to avoid back-and-forth sampling.

Case study snapshot — startup growth using Portugal

A Berlin eco-streetwear startup launched with 150 organic cotton t-shirts made in Portugal. They used GOTS certified fabric and started with DTG prints to test styles. Over two years they scaled to 10,000+ units while maintaining quality and fast EU distribution — a clear illustration of how Portugal’s low MOQ and quality advantage support startup scaling.

How to verify manufacturer credibility

Ask for documented proof: manufacturing certifications, recent audit reports, references from other brands, and photographic proof of in-line production. Where possible, request a factory visit or hire a third-party QC company to inspect pre-shipment samples. Portuguese manufacturers are typically open to providing production documentation and sample photos to build trust.
