Category file · Blank T-shirts
Blank T-shirts built for the print, not just the photo.
Jersey, interlock, and heavyweight cotton from 150 to 320 GSM. Send the WWTop Yupoo silhouette you want; we turn the drop shoulder, body width, and surface into a specification the next run can repeat.
Fabric weights and MOQs below are planning ranges. Final values are confirmed in the signed specification.
Catalogue lens
Read the tee photo in three layers.
The front of a T-shirt is the least useful part of a sourcing reference. The fit block, the fabric surface, and the decoration method are what determine the quote and whether the second run looks the same.
Oversized is a measurement, not a mood
A boxy drop-shoulder tee and a relaxed set-in tee can look similar on a hanger. We record chest width, body length, shoulder drop, sleeve opening, and hem width before sampling.
The photo cannot show GSM or shrinkage
A 180 GSM jersey and a 240 GSM heavy jersey can be photographed to look alike. The specification states composition, measured weight, shrinkage after washing, and colour tolerance.
Place the print before the fabric is booked
Screen print, DTG, puff, and embroidery each need a different surface and stabilisation. Send the artwork size and placement with the reference, not after the sample is made.
A branded tee can be an internal fit reference only. The production file must remove all brand identifiers, use your own artwork, and avoid protected logos, prints, or trade dress.

Choose a weight for the job, not for a number.
GSM is a useful starting point, but it is not a quality score. Yarn count, stitch density, finish, and shrinkage decide how the shirt actually wears and prints.
Scroll the table sideways if needed.
| Weight | Fabric feel | Typical use | What to check |
|---|---|---|---|
| 150–180 GSM | Light jersey | Warm climate, layering, fitted retail tees | Check opacity in light colours |
| 180–220 GSM | Midweight jersey | Everyday retail blanks, screen print, DTG | The most common starting point |
| 220–260 GSM | Heavy jersey | Structured drape, premium basics | Check shrinkage and hand-feel |
| 260–320 GSM | Ultra-heavy jersey | Boxy fits, heavyweight programs | Confirm drape and needle size |
Single jersey
Light, stretchy, print-friendly. The default for retail tees and promotional runs.
Interlock
Denser and smoother on both faces. Better shape retention for premium basics.
Heavy jersey
Structured drape for boxy fits. Check needle size, seam bulk, and shrinkage first.
Construction
The details that separate a sample from a repeat order.
A T-shirt can match on weight and still miss on collar recovery, shoulder slope, or side-seam twist. Those are construction decisions, not fabric decisions. They belong in the first specification.
- Collar: ribbed neckband with the stated recovery, or a taped self-fabric collar.
- Shoulders: taped seams prevent stretch on lightweight jersey.
- Sleeves: set-in or drop-shoulder, with a stated sleeve length and opening.
- Hems: double-needle or coverstitch, with stitch density recorded.
- Side seams: tubular or cut-and-sew; tubular changes the fit and print panel.
- Labels: neutral size and care labels, or your own private label.
Watch the “soft” claim
Hand-feel can be changed with washing, silicon finishes, or brushing. Ask what happens after five washes, and put the answer in the sample comment sheet — not just the sales message.
Print compatibility
Screen print, DTG, and embroidery each need a different surface. A shirt that prints well may not embroider well at the same weight. Specify the decoration before the fabric is booked.
Quality checks
What we want to see before bulk.
These checks are written into the sample approval and the final inspection criteria.
Weight and shrinkage
Measured weight against the spec, plus shrinkage after the agreed wash cycle.
Measurements and seams
Critical measurements within tolerance, flat seams, clean hems, and no twist after washing.
Lab dip and lot tolerance
Approved lab dip, light-source check, and a stated tolerance between production lots.
Adhesion and placement
Placement against the marker, wash durability, and no ghosting or strike-through.
Labels and thread
Label content, placement, thread match, and no brand marks from another company.
Carton and count
Size ratio, polybag, carton mark, and a count that matches the packing list.

What to send
A better brief produces a better quote.
You do not need a full tech pack for the first conversation. You do need enough detail to separate one option from another: fabric, fit, decoration, colour count, quantity, and destination.
If you already sell a tee, send an unbranded sample or a measurement chart. If you are starting from scratch, describe the customer and the use. We will map the fabric and construction options from there.
FAQ
Questions buyers ask
If your question is not here, send a brief. We answer in plain language, with conditions.
Can you match an oversized tee I saw on WWTop Yupoo?
Often, yes — as an original unbranded product. Send the listing or clear photos plus the measurements you want. We use the reference to discuss silhouette, fabric surface, and decoration placement, then write a new specification. We do not reproduce the brand’s logo, artwork, or distinctive trade dress, and the final garment must carry your label or no label.
What GSM should a blank T-shirt be?
A lightweight 150–180 GSM jersey suits warm climates and retail packaging. 180–220 GSM is the common midweight band for everyday retail blanks. 220–260 GSM feels substantial, and 260–320 GSM is a structured, boxy heavyweight. The right number depends on the fit, the opacity you need, and whether the shirt will be printed.
What is the minimum order for blank T-shirts?
Stock blanks may start around 50–100 pieces depending on colour. A custom-dyed or private-label run usually starts around 100–300 pieces per colour because fabric is booked for the order. The written quote states the minimum per colour and per size.
Which fabric is better: jersey or interlock?
Single jersey is lighter, stretchier, and the standard for printed tees. Interlock is denser, smoother on both faces, and holds shape better; it suits premium basics and heavier drape. Both can be cotton, cotton-rich, or blended, but the specification and shrinkage results matter more than the name.
Can you match a T-shirt I already sell?
Often, yes. Send an unbranded sample or clear construction details: fabric weight, measurements, shoulder construction, collar type, stitch density, and trims. A branded garment can be used as an internal fit reference only if the final product removes all brand identifiers and does not copy protected artwork or trade dress.
What decoration methods affect the spec?
Screen print needs a stable, smooth surface and controlled shrinkage. DTG needs a fabric and pretreatment compatible with the printer. Embroidery adds weight and can distort a light jersey. Specify the decoration before the sample so the fabric, fit, and stabilisation are chosen for it.
How long does a T-shirt sample take?
A stock-fabric sample usually takes 10–15 business days after the specification and size are approved. A custom-dyed or custom-knit fabric adds sampling and dyeing time. Freight is separate and depends on the destination.
