Laser on Jeans vs Fabric
If the pattern requires continuity across the pockets, the laser must be applied after the jeans are sewn, as shown in the photo on the left. For patterns that do not require symmetrical continuity, the laser is applied directly all over the fabric before manufacturing.
Sizing in Kids Jeans
Sizing in Women Jeans
Size charts that follow XS-S-M or 34-36-38 are typically graded with a 2 cm increment on the half-waist and 4 cm on the total circumference, but American sizing is different. Going from size 25 to 26, it is graded by 1.25 cm at half-waist and 2.5 cm (1 inch) around the total circumference, just like men’s pants. As with men’s pants, due to high-waist and low-waist styles, a size 36 in women’s pants may not measure the exact same total waist circumference across every model.
AMERICAN SIZING VS EUROPEAN
Sizing in Men Jeans
The most common sizing scale in men’s jeans runs as 30-31-32, and so on. Pattern grading is based on a 2.5 cm (1 inch) difference in total waist circumference between each size, which equals 1.25 cm for the half-waist measurement. Other dimensions are adjusted accordingly to maintain the overall fit and silhouette of the pants. The inseam length can always be customized based on customer preference.
However, a size 32 may not have the exact same measurements across every pair of jeans. This depends heavily on where the pants sit on the body, with rise styles—such as high waist or low waist—being the primary factors behind these variations.
While shorter inseams are preferred in southern countries, inseams 5–10 cm longer are favored in northern countries.
32 size jeans also is not same in every brand.
Custom Button Manufacturing
Custom buttons have a minimum order quantity (MOQ) of 5,000 pieces. We can provide design work for your brand upfront. Custom brass buttons generally cost €200, while Zamac buttons cost €400 (prices for enameled or other specialty button types may vary depending on the design). Since molds are required for production, we are unable to provide physical samples before the final run.
Brass vs Zamac Buttons
Zamac vs. Brass: Technical & Production Comparison
| Feature / Metric | Zamac (Zinc Alloy) | Brass |
| Primary Base Metal | Zinc (alloyed with aluminum, magnesium, copper) | Copper & Zinc alloy |
| Manufacturing Method | Die-Casting: Liquid metal is injected into a steel mold cavity. | Stamping: High-pressure press stamps the shape from a flat metal sheet. |
| Design / Logo Capability | Excellent (3D): Perfect for complex, curved shapes, sharp relief details, hollowed backs, and intricate borders. | Good (2D): Best for flat or slightly domed surfaces, simple embossed/debossed line work. |
| Average Mold Fee (approx.) | Higher: ~€400 (requires precision steel injection molds). | Lower: ~€200 (requires stamping dies). |
| Weight & Feel | Heavy & Solid: Feeling of premium luxury due to the solid cast density. | Lightweight: Hollow-backed shell wrapped around a core pin. |
| Rust & Wash Resistance | Moderate: Naturally oxidizes if the protective electroplating layer chips during harsh stone or acid washing. | Excellent: 100% rust-proof. Extremely durable under heavy industrial chemical washes. |
| Tensile / Pull Strength | Good, but more rigid. Extreme shear stress can cause it to snap. | Excellent. Ductile metal that bends rather than breaks under heavy physical stress. |
| Needle Detector Test | Riskier: Low-purity alloys can contain trace ferrous elements that trigger detection machines. | Highly Safe: Pure brass is non-magnetic, ensuring zero false alarms during retail export scans. |
Which one should you choose?
Brass is way more classic. If button is not centerpiece of your model brass is safer. Diesel, G-Star RAW, Replay, Calvin Klein Jeans, Armani Exchange kind of brands use zamac buttons.
Choose Zamac if your design features a prominent, highly detailed 3D brand logo, you want a heavy “premium weight” button, and you have the budget to cover the higher upfront mold costs (€400).
Choose Brass if you want a classic heritage look with a lower mold investment (€200), and you must guarantee trouble-free needle detection for export.
Rivets at coin pocket
The pants in the photo are 14 oz. Rivets can also be attached to the watch pocket, but there is a possibility they might fall off in the long run. While the tack pierces through two layers of fabric at the pocket edges, it goes through 4 layers at the watch pocket, and the fabric becomes as stiff as a rock. Because of this, applying capped or nipple rivets to the watch pocket is very risky. Nipple rivets are more durable due to the tack traveling a longer distance, but using them on the watch pocket is still a major risk. On thinner pants, any kind of rivet can be used on the watch pocket.
Zip vs Button Fly
Zip is flexible, button is rigid
Skinny jeans always use a zip fly. On 100% cotton jeans, depending on the style, the fly can be either a zipper or a button fly. A button fly used to be thought of mainly as a men’s-jeans thing, but these days it’s used even on women’s jeans — and honestly, the men’s/women’s divide in fashion is closing up more and more anyway.
With a button fly, the front rise comes out to the same measurement regardless of size. With a zipper, we have the option of using a shorter zip on smaller sizes, but as long as there’s enough room in the front rise, there isn’t much difference between the two. It used to be that the zipper-versus-button choice on the fly varied from country to country, but that’s no longer really a thing.
Bottom line: if you’re undecided, a zipper is always the safer. And it’s not something that affects sales one way or the other.
Neon Color Production
Dyeing Neon vs. Normal Colors: Side-by-Side Comparison
| Factor | Normal Colors | Neon Colors |
|---|---|---|
| Dye Chemistry | Established reactive, vat, acid, or disperse dyes with proven formulations | Specialty fluorescent dyes; often limited dye class options; newer chemistry |
| Lightfastness | Good to excellent (often 5–8/8 on standard tests) | Poor to fair (typically 2–4/8); fades noticeably in 1–2 months of sun exposure |
| Wash Fastness | 4–5/5 typical (minimal color loss over 20+ home washes) | 2–3/5 common; bleeding and crocking risk increases; dye can transfer to other garments |
| Rubbing/Crocking | Low (fiber-bound, especially vat dyes) | High; loose dye particles on surface make crocking a real problem, especially on pale fabrics |
| Temperature Stability | Stable 40–90°C; many dyes improve at higher temps | Degrades above 60°C; brightness loss accelerates; high temps can cause shade shifts |
| pH Sensitivity | Moderate; ranges accommodate small pH shifts | Extreme; narrow pH window (±0.5 can alter shade noticeably) |
| Leveling/Evenness | Relatively forgiving; standard leveling agents work reliably | Difficult; uneven strike-off is common, especially on tight weaves like gabardine |
| Penetration on Tight Weaves | Adequate even on gabardine with standard conditions | Poor; tight weave resists fluorescent dye molecules; surface-heavy dyeing common |
| Cost per kg | $8–25 typically | $20–100+ (4–10× more expensive) |
| Sourcing & Consistency | Wide supplier base; batch-to-batch variation low | Limited suppliers; batch variation higher; discontinued shades are common |
| Regulatory Approval | Standard OEKO-TEX, ZDHC, EU restrictions well-known | Stricter scrutiny; some fluorescent brighteners banned in EU; compliance documentation harder |
| Sampling Cost | Low (small dye quantities sufficient) | High (need more dye to get readable neon effect; failed trials are expensive) |
| Customer Expectations | Durability built into product positioning | Customer often unaware neon = short-lived; complaints common |
| Post-Treatments | Standard finishes (softening, anti-static) suffice | Require cationic fixatives to improve wash fastness; adds process steps & cost |
| Storage Stability | Dyed fabric remains stable 6–12 months in cool, dry conditions | Neon dyes fade during storage; accelerated by light and humidity; shelf life 2–4 months |
Neon Fabric Manufacturing
Instead of dyeing a PFD white product, we can produce fabric directly in neon color. When manufacturing neon color fabric, we can apply a Teflon coating to the fabric to increase color durability. This imparts a slight stiffness to the fabric, but we overcome this with a rinse wash.
Pantone Code vs Real Product
Products can be dyed directly from a Pantone code, but only after the Pantone specification has been tested and validated through lab work on the specific fabric being used. Keep in mind that the same Pantone code may not produce identical results across different fabrics — particularly if you’ve previously matched that code to a different fabric.
