A long-sleeve polo is the most useful fall shirt because it does the job of three: it is softer than a dress shirt, smarter than a T-shirt, and sits neatly under a blazer or overshirt without a collar to fight. Wear it alone with trousers, under a knit blazer, or tucked with a belt for dinner.
Why is a long-sleeve polo so useful in fall?
A long-sleeve polo gives you a collar and long sleeves in a knit, which is exactly what a fall day between 8 and 18 degrees calls for.
A dress shirt needs ironing and looks stiff on its own at the weekend. A T-shirt looks underdressed at a restaurant or in a business casual office. A short-sleeve polo looks like golf in October. The long-sleeve polo is the one shirt that crosses all of those lines.
It also solves a layering problem. A woven shirt collar under a knit blazer or a sweater often curls, crumples, or fights the lapels. A knit polo collar lies flat. It is the reason many men who say they do not like blazers suddenly do once they try one over a polo.
Most men own several short-sleeve polos and no long-sleeve ones. That is the gap this post is about.
Pima pique or Tencel knit: which long-sleeve polo should you buy?
Buy the Psycho Bunny pique if you want an easy-care everyday polo; buy the Blue Industry Hayes if you want a dressier, finer knit for evenings and the office.
The Psycho Bunny Classic Long-Sleeve Pima Cotton Pique Polo in Black ($138, also in white) is 100% Pima cotton in a classic pique knit. Pima is a long-staple cotton, which is why it feels smooth rather than scratchy, and the pique texture gives it enough body to hold its shape under a jacket.
The Blue Industry Hayes Polo in Navy ($275, also in black) is a different animal: 54.6% Tencel, 22% nylon, 19.5% cotton and 3.9% silk, with buttoned sleeves and a signature arm patch. The Tencel and silk give it a soft drape and a slight sheen that reads dressier than cotton pique. The trade-off is care: it is dry clean only.
My advice: start with the Psycho Bunny in black. Add the Hayes in navy when you want a polo you can wear to a good dinner.
How should a long-sleeve polo fit?
A long-sleeve polo should fit close through the chest without pulling at the buttons, with sleeves that end at the wrist bone and a hem that covers your belt.
Shoulder seams belong on the edge of your shoulders. If the fabric drapes in a fold under your arms, it is too big; if the placket gapes, it is too small. Sleeves are the most common problem: a long-sleeve polo with long sleeves bunches at the wrist and looks sloppy under a jacket.
The Hayes is listed as true to size in a slim fit, so take your usual size, or go up one if you are broad in the chest. For Psycho Bunny sizing, see our Psycho Bunny sizing guide, or call us and we will check a size for you.
What do you wear with a long-sleeve polo?
Wear a long-sleeve polo with trousers or dark jeans, leather shoes or clean sneakers, and a knit blazer when you want to dress it up.
Office: the white Psycho Bunny polo tucked into the Alberto Pipe Two Tone in Brown ($345), a five-pocket trouser in a textured chocolate weave, with a brown belt and brown leather shoes. Comfortable all day and smart enough for a client.
Dinner: the Hayes in black under the 7 Downie St. Terry Denim-Effect Knit Blazer in Navy ($595), a soft knit blazer with natural stretch and a notch lapel, with dark jeans. The polo collar sits flat under the lapels. More on this pairing in smart casual for the office.
Weekend: the black Psycho Bunny polo untucked, sleeves pushed up, with dark jeans and white leather sneakers.
Common questions
Should a long-sleeve polo be tucked in?
Tuck it with trousers and a blazer; leave it out with jeans. If the hem falls below the middle of your back pocket, it is too long to wear untucked.
Can you wear a long-sleeve polo under a sweater?
Yes. A polo collar over a crewneck sweater looks neat and is warmer than a shirt alone. Keep the colours simple: white or black under navy or grey.
Is a long-sleeve polo business casual?
In most offices, yes, especially in a solid colour with trousers. The finer Hayes reads more formal than cotton pique.
How do I wash a Pima cotton polo?
Follow the care label, wash cold, and dry flat or on a hanger to keep the collar and length where they should be.
