The small fabric hook on the back of a shirt—right at the crease under the shoulder yoke—is one of those details you see every day but rarely question. Today, it’s mostly decorative, but it has an extremely practical and fascinating history.
Here’s the true purpose of this so-called “locker loop”:
- The real purpose: Wrinkle-free hanging
The loop was made famous in the 1960s by the legendary American shirt brand Gant.
The problem: Back then, most men (especially students) didn’t have hangers in their dorms or locker rooms, or simply not enough closet space.
The solution: The loop allowed the shirt to be easily hung on a hook on the wall or in a locker. By positioning the collar at the yoke, the shirt remained largely wrinkle-free and retained its shape without the collar stretching out.

At elite American universities (Ivy League), the collar loop quickly became a silent means of communication regarding students’ relationships:
In a committed relationship: If a student was in a committed relationship, he (or his girlfriend) often cut off the loop. This signaled to everyone on campus: “I’m taken.”
Single status: If the loop was still attached, everyone knew the wearer was available.
The souvenir: Sometimes women also wore their boyfriends’ cut-off collar loops as a kind of “college ring” substitute.
Why do they still exist today?
With the advent of inexpensive wire and plastic hangers, the collar loop quickly lost its practical use.
The fact that brands like Gant, Ralph Lauren, and Barbour still produce them today is purely due to tradition and style. They have remained a visual hallmark of the classic “preppy” or “Ivy League” look.
Fun fact: Because the loops tended to get caught on objects and break off in everyday life—especially when sitting down quickly or in the washing machine—students jokingly called them “fruit loops” or “sync loops” back then.
