T-Shirts — CSSBuy Spreadsheet Guide

T-shirts are the lowest-risk category in the CSSBuy ecosystem. They ship cheap, compress well, and offer the fastest way to test a factory's print and fabric quality before committing to larger orders.

If you are new to the CSSBuy spreadsheet, t-shirts are the logical starting point. They combine low unit cost with minimal shipping weight, which makes them ideal for testing fit, print durability, and fabric hand-feel before moving up to hoodies or outerwear. In 2026, the dominant story in this category is the rise of heavyweight blank-tier cotton. Many spreadsheet listings now compete on GSM and seam construction rather than just print accuracy. For buyers in the US, t-shirts also offer the safest customs profile because they are low-value and easily declared. The key is to treat your first t-shirt order as a calibration purchase: order two sizes or two factories, document the differences, and use that knowledge to inform your future spreadsheet picks.

Popular Directions in T-Shirts

Heavyweight Blanks

240GSM+ cotton. Check collar rib construction and shoulder seam binding.

Graphic Prints

Screen vs. DTG matters. Screen holds longer; DTG allows more color complexity.

Vintage / Washed

Single-stitch hems and soft wash are the visual signatures of this sub-style.

Oversized Boxy

Drop-shoulder and extended length. Verify width-to-length ratio before buying.

Pre-Purchase Checklist

1Order two sizes if you are unsure about factory grading.
2Check whether the print is screen or DTG; it changes care instructions.
3Request a close-up of the collar stitch to gauge construction quality.
4Budget for multiple t-shirts in one parcel to amortize shipping.

QC Observation Points

Collar rib rebound after stretch
Shoulder seam alignment and stitch count
Print registration against seams and hems

Fabric weight consistency front-to-back

Common Mistakes

•Buying based on thumbnail alone without reading fabric notes.
•Assuming all oversized fits share the same proportions.
•Washing hot on the first cycle and shrinking a calibration order.
•Ignoring dye transfer warnings on dark graphic prints.

Size & Fit

T-shirt sizing in this ecosystem runs large by US standards. A 'medium' often fits like a US large. Check the length measurement first; chest width second. If you are between sizes, size down for a standard fit and up for an oversized look.

Material Notes

Ring-spun cotton at 200-260 GSM is the standard for quality blanks. Carded open-end cotton below 180 GSM will feel rough and pill quickly. Slub cotton adds texture but can distort print registration.

Risk Reminders

Dark prints on light fabric can crack if cured at low temperature.

Garment-dyed batches vary in tone between restocks.

Some listings use retail photos instead of actual batch shots.

T-Shirts FAQ

Is 250 GSM too thick for summer?

It depends on your climate. 250 GSM is breathable in dry heat but can feel heavy in humidity. For hot summers, aim for 180-200 GSM ring-spun.

How do I prevent print cracking?

Wash inside-out on cold, hang dry, and avoid high-heat tumble cycles. Screen prints are more forgiving than DTG.

Should I buy blanks or printed first?

Blanks are better for testing fit and fabric. Once you know your size, printed orders carry less risk.

Why do the same sizes vary between factories?

Each factory grades from its own pattern block. A size chart from Factory A does not apply to Factory B. Always measure against your own body or a favorite shirt.
