A polo shirt has four things that decide whether it works: how it is cut, what it is knitted from, how it is finished, and how it is washed. Almost everything written about buying one skips straight past the first three to talk about brands.
This guide takes them in order. Every figure in it comes from a manufacturer’s own product page or size chart, and where a brand does not publish something, it says so rather than filling the gap with a plausible number.

Fit: The Only Measurement That Settles It
Why the Size on the Label Means Nothing
There is no mandatory clothing size standard in the United States. The 1958 National Bureau of Standards system was made voluntary in 1970 and withdrawn entirely in 1983, and the ASTM standard published in 1995 to replace it was never widely adopted.
Nothing obliges a brand to cut a medium to any particular chest. “Slim fit” is a word the brand chose, not a specification it met, which is why sizing down works on one shirt and produces a straitjacket in the next.
Drop, and Why Your Waist Decides the Hem
Tailoring has a word for the shape a shirt is cut for. Drop is the difference in inches between chest and waist — six is the traditional regular build, seven is trim, eight is slim.
Polo brands do not publish a drop figure, and any article quoting one for a knit shirt has invented it. What the idea explains is the complaint nobody diagnoses correctly: if your chest and waist are close together, a shirt cut for a large drop billows at the hem even when the chest fits. That is a hem problem, and sizing down will not fix it.
The reverse is the muscular build’s problem — a large drop, where a shirt that fits the chest has a waist you could camp in. Both cases are covered in more depth in the polo shirt fit guide.
The Three Seams Worth Checking
The shoulder seam should sit on the corner of your shoulder, not down your arm. The sleeve should end around mid-bicep. The hem should finish somewhere below the belt line but above the middle of the fly.
Body length is the one brands rarely commit to in writing. Tommy Hilfiger is an exception, describing its slim polo as tailored throughout and cut shorter, and publishing a 28-inch body length for a medium. If you are short in the torso, that single stated figure is worth more than any fit adjective.
If you are narrow through the chest, the shirts cut for that build are in best polo shirts for skinny guys.
Fabric: Knit Structure Matters More Than Fiber
Piqué Is a Knit, Not a Material
This is the most common error in polo shirt copy, and it makes listings unreadable. Piqué is a knit structure. Cotton is a fiber. “Cotton piqué” describes both; “piqué fabric blend” describes nothing.
The raised waffle texture of piqué is what makes a polo hold its shape where a jersey T-shirt goes limp. Lacoste invented petit piqué for the L.12.12 in 1933 — a finer version of the same structure, and the reason that shirt feels unlike a supermarket polo of identical fiber content.
Mesh is more open and moves air. Jersey is smooth and flat and drapes like a T-shirt. Interlock is denser and heavier. All four can be 100% cotton and none of them wear alike, which is covered fully in the polo shirt fabric guide.
Where Stretch Helps, and Where It Does Not
Elastane appears in the middle of the market and disappears again at the top. Tommy Hilfiger’s slim polo runs 97% cotton with 3% elastane; Lacoste’s stretch mini piqué runs 94/6. Both are enough to change how a narrow cut behaves rather than just to justify the word on the label.
Above that tier the elastane goes away. Fred Perry’s M3600 and Lacoste’s original L.12.12 are both 100% cotton on purpose, because a rigid piqué holds a defined outline and that outline is the point of those shirts. Paying more takes the stretch away — a preference, not an upgrade.
Nobody Publishes GSM
Fabric weight in grams per square metre is the figure every buying guide tells you to compare. Across the brands checked for this site — Lacoste, Ralph Lauren, Fred Perry, Tommy Hilfiger, Hanes, Amazon Essentials — not one publishes it.
So it cannot be the basis of a comparison, however often it is quoted. And a heavier shirt is not automatically a better one: a heavy, loosely knitted piqué loses its shape faster than a lighter, tightly knitted one. Weight is a property, not a grade.
Construction: The Details You Can Check in Seconds
Buttons Tell You the Price
The most reliable tell on the whole garment. Lacoste finishes the L.12.12 with mother-of-pearl buttons taken from traditional shirting; budget shirts use pearlized plastic. Hold one to the light and turn it — mother-of-pearl shifts color across its surface and stays cool, plastic is uniform and warms in your fingers.
Placket count varies more than people expect. Two buttons is standard; Hanes fits three on the X-Temp, which shortens the neck opening noticeably.
The Collar Is What Fails First
A polo collar is knitted separately and attached, and how it is built decides whether the shirt still looks deliberate after twenty washes. A dense ribbed collar holds; a thin one curls at the points and never recovers.
Nike is unusually direct about this, stating that the ribbed collar on its Dri-FIT Victory polo is designed to help prevent curling. Most brands say nothing at all about it, which is itself informative. The full treatment is in how to stop a polo collar curling.
Size Range Is a Quality Signal
A brand that cuts XS to XXXL has graded its pattern properly across the range. Fred Perry publishes XS to XXXL against a 32 to 52 inch chest — naming the chest measurements, not just the letters. Hanes starts at S, so there is no XS at all.
If you are outside the middle of the range, the shirts cut for those builds are in best polo shirts for tall and big guys and best polo shirts for muscular guys.
Care: What Actually Destroys a Polo Shirt
Almost no polo dies of wear. They die in the dryer, on the wrong hanger, or from a wash routine that treats a knitted collar like a cotton T-shirt.
Heat is the main culprit, and it is also the lever if you want a shirt to shrink deliberately — cotton and cotton-polyester blends move by different amounts at different temperatures, which is the subject of how to shrink polo shirts. The routine that avoids shrinking one accidentally is in how to wash polo shirts.
Storage matters more for polos than for woven shirts, because a knit stretches under its own weight. Heavier shirts belong folded; the hanger question is covered in how to hang polo shirts.

Choosing a Polo Shirt FAQ
What is the single most useful thing to check before buying?
Your measured chest against the brand’s published garment measurement for that size. Very few brands publish one — Ralph Lauren is the notable exception — and where they do, it removes the guesswork entirely.
Is 100% cotton always better than a blend?
No. Cotton holds shape and looks more formal; a cotton-polyester blend wicks better and costs less. The most and least expensive shirts researched for this site are both 100% cotton, so fiber content is not a price ladder.
What GSM should I look for?
None of the major brands publishes fabric weight, so the question has no answerable form. Judge by knit structure and fiber composition instead, both of which are published.
How should a polo shirt fit at the shoulder?
The seam should sit on the corner of the shoulder. Further down the arm means the shirt is too big, and no amount of styling hides it.
Does a more expensive polo last longer?
Usually, but through details rather than fabric — mother-of-pearl buttons over plastic, denser collar ribbing, finer knits. Those change how the shirt ages, not how it fits.
Final Thoughts on Choosing a Polo Shirt
Measure your chest once and write the number down. That single figure, checked against what a brand publishes rather than against the letter on the tag, resolves more polo shirt purchases than every fabric debate combined — and it is the one step almost nobody takes.
