There are these two garments whose terms are sometimes mixed: the popover and the polo shirt (or "polo shirt").
The popover
The term "popover" describes a shirt with a half-button placket, which is therefore put on from the top. That's where its name comes from: popover = " to pop the shirt over your head ".
The popover has its roots in the Ivy League style of American students . It was Gant who launched this type of shirt in the 1960s as a more casual variation of the classic shirt.
Thus, the popover shirt can be made in a multitude of materials (flannel, oxford, etc.) but also with collars (buttoned, open, closed, official, etc.).
The polo shirt, or polo shirt
This garment was popularized by the extravagant Gianni Agnelli, illustrious executive of Fiat and pioneer of sprezzatura, who loved to wear it to be elegant and casual on the beaches of Capri.
The polo shirt is characterized by a polo material
In this sense, the polo shirt is a specific type of popover.
Good to know
*It is interesting to note that the term "polo shirt" also historically refers to OCBD
*We can also note that, ultimately, each brand names its products as it wishes:
- The G. Inglese brand, a pioneer in polo shirts, calls all its partial throat shirts polo shirts. So, some of their polo shirts are in pique cotton... and others are in linen or poplin (strictly speaking, they are more popover).
- Suitsupply on the other hand does not use the term "polo shirt" but always speaks of "popover". They have popovers in knit, denim, etc.
In idea, it's a bit like with the terms "jogpants" and "sweatpants" whose use is rather free.
Some style tips
Popover and polo shirts often fall somewhere between formal and casual. Adapt your outfit accordingly.
In themselves, they can be worn in the same way as a shirt: outside the pants for a casual look if the length allows it, inside the pants for a more structured effect.
