Custom Oversized T-Shirts

Oversized T-Shirt Manufacturer Bangladesh

Siatex Bangladesh is an oversized t-shirt manufacturer and exporter supplying boxy drop-shoulder tees to streetwear labels and skate brands in the USA, the UK, Germany, Canada and Australia. Every garment is knitted and sewn in Bangladesh to the buyer's fabric, fit and colour specification on a confirmed order, under the buyer's label.

Materials - Heavyweight cotton single jersey gives the body its drape and structure, knitted from carded open-end yarns for a dry hand feel or combed yarns where a cleaner print surface is briefed. A firm rib knit finishes the collar, holding the neckline flat.

Functionality - The dropped shoulder and chest width let air move in heat and leave room for layering over long sleeves in cold months. Sleeves fall to the elbow, hems sit low, and the flat chest carries big prints without a seam breaking the design.

Size - Adult ranges run from your size chart, with the oversized block graded on chest width, shoulder drop and body length together, so every size keeps the same relaxed proportion.

Customisation - Artwork leads: chest prints, back prints and sleeve hits placed to your guide, with washes, embroidery, labels and hangtags across the story. White, washed grey and khaki lead. Every oversized t-shirt is made to order under your brand: no ready oversized t-shirts sit waiting, and sewing begins when your order is confirmed.

Oversized T-Shirt Fabrics: Heavyweight, Slub and Washed Jerseys

Weight carries the silhouette: light cloth collapses on the body, heavy jersey holds the boxy line. Most labels brief a firm heavyweight knit, then soften it with wash, so the finished t-shirt holds its shape yet feels broken-in at once.

  • Heavyweight cotton single jersey for a structured drape
  • Carded open-end jersey for a dry vintage hand feel
  • Combed cotton jersey for a smooth print surface
  • Slub jersey with a soft irregular texture
  • Cotton elastane jersey with slight stretch
  • Garment-washed jersey for a lived-in finish
  • Pigment-dyed and dip-dyed cloth
  • Rib knit for collars and neckline tape
  • Other buyer-specified fabrics to your hand feel

Every quality is sampled in your colour before bulk knitting, so handle, drape and shrinkage are approved on the cloth itself. The same jerseys run through our t-shirt programmes, so regular and oversized fits in one drop share one cloth story.

Oversized T-Shirt Sizes, Fits and the Wide Block

An oversized block is not a regular pattern sized up. The pattern maker sets chest width and shoulder drop, then builds body and sleeve length around them, so the t-shirt hangs square on every size.

A ladies line is blocked separately beside the mens range on the same grading logic, so mixed stories sit consistently. Sleeve length is measured from the dropped shoulder point, as on our long sleeve t-shirt styles, and fit is proven on a sewn base size before grading is released.

Oversized T-Shirt Construction: Dropped Shoulders and Elbow Sleeves

Construction holds the volume: the shoulder seam sits low, the body falls straight, and nothing is nipped at the waist.

  • Shoulder seam dropped below the shoulder point
  • Wide body cut straight to the hem
  • Sleeves cut wide to the elbow
  • Ribbed collar band, wide neckline
  • Shoulder tape holding neckline shape
  • Deep coverstitched hems, cleanly finished

Garment-dyed styles are sewn before colour touches the cloth, with shrinkage allowed in the block, the same route our tie-dye t-shirt work follows. Side seams are set true against twisting in the wash; sleeves are eased into the dropped armhole for a smooth shoulder line.

Customising Your Oversized T-Shirt: Big Prints, Washes and Embroidery

The wide chest is the canvas streetwear prints are built on: a back print can run the garment’s full width, and placement is marked from the dropped shoulder line so artwork sits level on the t-shirt.

  • Oversize chest and back prints to your artwork
  • Sleeve prints and small embroidered hits
  • Garment wash, enzyme wash and pigment dye
  • Woven labels, hangtags and size stickers
  • Custom colours dyed to your palette

Labels in the Netherlands often pair a loud back print with plain washed bodies, letting the print carry the story. The ladies block takes the same decoration menu as our ladies t-shirt programmes, so one artwork story can drop in mens and ladies fits together.

Oversized T-Shirt Sampling and Product Development for Australia and UK Buyers

Sampling turns your tech pack or reference garment into a sewn t-shirt before bulk is committed.

The block is patterned, cloth and trims confirmed, and a pre-production sample is made in your base size with the drop checked against your chart.

Sleeve proportions are settled in the same round, and plain and pocket versions are sampled together, the pocket set with the discipline of our pocket t-shirt range, so a mixed drop approves at once. Australian labels adjust the drop in small steps from a best-selling reference; UK buyers mark the shoulder measurement as the control point.

Oversized T-Shirt Quality Assurance and Production Follow-Up

A wide garment shows faults clearly: a twisted seam or uneven drop reads at a glance, so checking concentrates on symmetry and proportion.

As a family-run manufacturer, we hold the approved sample as the standard for every later t-shirt.

  • Cloth shade, weight and shrinkage checked pre-cutting
  • Shoulder drop and chest width measured per size
  • Print placement checked against your artwork
  • Collar rib recovery checked after washing
  • Measurements reviewed against your chart pre-packing
  • Final garment-by-garment inspection before cartons seal

Any garment falling short of the approved standard is remade or set aside before packing, never passed through.

Ordering Your Oversized T-Shirt: Terms, Approvals and Repeat Orders

To start, send a tech pack, reference garment or photographs of the t-shirt fit you want built. With 37 years of experience behind us, we answer with cloth choices, a sampling route and a price per style from your specification.

Everything commercial is settled on paper before cutting begins: payment route, delivery timing and quantities per style, written into the order confirmation. Buyers in Japan usually take the full size set first, proving the block across the range. Approvals stay with you at sampling, pre-production and dispatch, with pattern, artwork and packing details kept on file.

Shipping and Delivery of Your Oversized T-Shirt Order

Finished garments are folded wide to protect the shoulder line, each t-shirt laid flat with tissue; cartons are marked to your template. Consignments ship from Chattogram port, with the UAE served on regular sailings for labels selling there.

Freight is booked against your delivery window: sea for bulk, air when a launch cannot wait. Weights and carton dimensions go out before booking, and dispatch is confirmed by your merchandiser as the goods leave Bangladesh.
