The cheapest item that decides how you look
T-shirts are the least expensive part of most oopbuy clothes orders and the most frequently worn. They are also where the widest quality range hides, because a photo cannot show weight, opacity or how a collar will behave after ten washes. Getting tees right is the highest-return clothing skill there is.
This guide covers the numbers, the collars, the prints and the shrinkage, and applies the same logic to polos at the end.
Fabric weight, in plain terms
Cotton jersey is sold by weight. The number tells you how the tee will hang and how long it will last.
| Weight | Character | Notes |
|---|---|---|
| 140–160 gsm | Very light, slightly sheer | Summer only; white can show through |
| 170–190 gsm | Standard light tee | Common budget weight |
| 200–220 gsm | Mid weight, opaque | The everyday sweet spot |
| 230–260 gsm | Heavyweight, structured | Holds shape; warmer; less drape |
| 280+ gsm | Very heavy, almost sweatshirt | Statement piece; can feel stiff |
Weight is a planning figure, not a guarantee. Two 220 gsm tees can differ in how they feel depending on the yarn and the knit. But between a 160 and a 240, the difference is unmistakable, and the listing usually states which it is trying to be.
Composition matters as much as weight
Pure cotton is breathable and takes print well. A small percentage of elastane adds stretch and recovery, which helps a fitted tee keep its shape. Polyester blends dry faster but can pill and hold odour. Viscose or modal blends drape softly and feel cooler, but they stretch more and need gentler washing.
For everyday tees, a mid-weight cotton or a cotton-elastane blend is the safest choice. For a boxy streetwear tee, a heavier pure cotton holds the silhouette better.
Collars: the detail that ages first
A tee looks old when the collar waves. That happens because the ribbing is thin and the seam is single-stitched. Look for:
- A ribbed collar, ideally with a visible band rather than a folded self-fabric strip.
- Twin-needle stitching at the neck, which resists stretching.
- Taped neck seam inside, which stops the shoulder line distorting.
These details are visible in listing photos if you zoom. They are also visible in QC photos, which is where you should check them before approving.
Fit: three shapes and who they suit
- Regular — follows the torso, hem near the hip. The default for layering.
- Boxy — wider chest, shorter body, often dropped shoulder. Works with wide trousers; looks odd with slim ones.
- Longline — extended body, sometimes curved hem. Sits below the hip and changes the whole silhouette.
Compare body length as carefully as chest width. A tee that is 4 cm shorter than you expect will sit at the waistband rather than over it, which is a different look entirely. For layering under a hoodie or jacket, a regular fit with a slightly longer body is the most useful.
Prints and embroidery
Printed tees are where QC earns its keep. Check:
- Placement — centred on the chest, level with the shoulders.
- Sharpness — edges of the graphic are clean, not fuzzy or bleeding.
- Adhesion — no lifting corners, which usually appear after the first wash.
- Coverage on dark colours — a white print on a black tee should be opaque, not grey.
Embroidery is more durable than print but harder to judge from a distance. Ask for a close-up if the design is detailed.
Shrinkage and the first wash
Cotton jersey can shrink 3 to 5 percent on a hot wash, more if it is unmercerised. That is often around 2 cm of body length. If you are between sizes on a pure cotton tee, the larger one is usually the safer choice, and washing cold limits the effect.
Heavyweight cotton shrinks less in practice because the knit is denser, which is another argument for buying at 220 gsm or above if longevity matters.
Polos: the same rules with a collar
A polo is a knit shirt with a placket and collar, and it fails in different places. Check the collar stand — a floppy collar that will not sit up looks tired immediately. Pique cotton is the classic fabric: breathable, structured, slightly textured. It weighs more than jersey at the same thickness because of the knit structure.
Fit matters more on a polo than a tee, because the placket and collar draw the eye. A polo that is too tight pulls at the buttons; one that is too loose collapses at the shoulder. Compare chest width and shoulder width together.
| Garment | Typical weight | Key check |
|---|---|---|
| Light tee | 160–180 gsm | Opacity in white |
| Everyday tee | 200–220 gsm | Collar ribbing |
| Heavy tee | 240–280 gsm | Body length after wash |
| Pique polo | 200–240 gsm | Collar stand and placket |
Ordering tees in multiples
Tees are the cheapest way to fill a parcel. Three plain tees add well under a kilogram and cover most of the week. Buy the same listing in two colours rather than two different listings, so the fit is predictable. And buy one first if the listing is new to you: a single tee is a cheap test of a seller's sizing before you commit to five.
For the rest of the wardrobe, the hoodie guide covers the next layer up, and the clothing overview explains how these pieces fit into a full order.
