Custom leavers' shirts become must-have UK school tradition

People are more okay with being who they are at the end of term.
A young designer reflects on how custom leavers' shirts have given teenagers permission to express themselves.

At the close of secondary school in England, a quiet ritual has transformed into something more deliberate: students are no longer simply passing around shirts to be scribbled upon, but commissioning and crafting custom garments that speak to who they are before the world asks them to become someone else. The leavers' shirt has become a small monument to identity — stitched with inside jokes, cultural references, and the signatures of those who witnessed five formative years. In this convergence of nostalgia, commerce, and self-expression, a generation is choosing to mark its transitions not with a blank canvas, but with a declaration.

  • The old tradition of plain shirt-signing has been overtaken by a deliberate, design-driven movement that demands hours of creative planning from students already under exam pressure.
  • A wave of teenage entrepreneurs — some barely out of secondary school themselves — has built real businesses around the trend, with one seller moving over 5,000 shirts and working through the night for months each year to meet demand.
  • Social media platforms like TikTok and Etsy have turbocharged the phenomenon, turning individual creative projects into viral templates and storefronts with six-figure followings.
  • For students, the shirt carries emotional weight beyond aesthetics — it is a physical anchor to friendships and feelings that might otherwise dissolve in the blur of transition.
  • The trend is landing as a cultural institution: some schools now hold unofficial design competitions, and students report that shared shirt aesthetics are already sparking new friendships before leavers' day even arrives.

Walk into a secondary school in England right now and you'll find Year 11 students doing something that has little to do with GCSE revision. They're designing custom leavers' shirts — elaborate, personal garments featuring anime characters, brand parodies, Spotify playlists, and inside jokes — that will serve as the unofficial uniform of their final day and a permanent keepsake of the years behind them.

The old tradition of passing around a plain shirt for classmates to sign has given way to something far more intentional. Students spend hours on Pinterest and TikTok hunting for inspiration, commissioning artists, or attempting hand-painted designs themselves. The trend has grown large enough to sustain a new generation of small businesses, with platforms like Etsy now stocking thousands of options.

Joy Nzau, twenty, began making shirts three years ago as a personal project for her sister's leaving day. It became a side business with millions of social media views. She sees the shirts as more than merchandise. "The shirt is a physical memory," she said, "a reminder of fun with all your feelings and nostalgia." She also believes the trend has quietly given teenagers permission to be themselves at a moment when conformity usually wins. "People are more okay with being who they are at the end of term."

The commercial scale is striking. Sydney Evans, nineteen, from Essex, has sold over 5,000 shirts since launching on Etsy five years ago and now runs the business full-time, working through the night alongside her father during the summer rush. Kavanna, also nineteen, from Wigan, launched her shirt business in early 2025 and has already produced more than 350 custom designs.

For students like Aarushi, a fifteen-year-old from Warwickshire planning a Guardians of the Galaxy-themed shirt, the design process has become part of the ritual itself — a social event, a creative outlet, and a counterweight to exam stress. "There's definitely a pressure to have a good shirt," she admitted, "but it's a good memory as it's your last day of secondary school." She's also hoping the shirts will do something unexpected: help her spot kindred spirits. "You can spot similar personalities with similar shirts and that could spark new friendships."

What began as a way to preserve memories has quietly become a statement of identity — a final declaration of who you are before the next chapter begins. Some schools have even started running design competitions, turning leavers' day into an unofficial fashion show. The shirt now sits at the intersection of nostalgia and self-expression, carrying the weight of an entire era of a young person's life.

Walk into a secondary school in England right now, and you'll find Year 11 students hunched over their desks doing something that has nothing to do with GCSE revision. They're designing shirts—not just any shirts, but custom leavers' shirts that will become the unofficial uniform of their final day, covered in inside jokes, favorite brands, anime characters, and the signatures of everyone who mattered to them over the past five years.

This is not your parents' leavers' day. The old tradition of passing around a plain shirt for classmates to scribble on has evolved into something far more deliberate and permanent. Students now spend hours on Pinterest and TikTok hunting for design inspiration, commissioning artists, or attempting their own hand-painted creations. Some shirts feature parodies of beloved brands like Asda, Nando's, and Greggs. Others showcase Spotify playlists, anime obsessions, or inside references that only the wearer's closest friends will understand. The trend has become so widespread that online marketplaces like Etsy now stock thousands of options, and a new generation of teenage entrepreneurs has built thriving businesses around it.

Joy Nzau, twenty years old from east London, started making these shirts three years ago as a hobby for her sister's leaving day. What began as a personal project has turned into a side business with millions of views across social media. She paints designs inspired by fast-food chains and supermarkets, and her work has resonated with students hungry for something more meaningful than a blank canvas. "I felt on my own after leaving school," she explained. "The shirt is a physical memory, a reminder of fun with all your feelings and nostalgia." What strikes Nzau most is how the trend has given permission for self-expression at a time when teenagers often feel pressure to conform. "Everyone wants to be the same in secondary school and this is different," she said. "People are more okay with being who they are at the end of term."

The commercial side has exploded. Shirts by Niamh, a TikTok account with over 100,000 followers, charges up to £35 per shirt, embellishing them with glitter, gems, spray paint, and feathers. Kavanna, a nineteen-year-old from Wigan, started her shirt business at the beginning of 2025 and has already produced more than 350 custom designs. Sydney Evans, also nineteen, from Harlow in Essex, has sold over 5,000 shirts since launching on Etsy five years ago. She works full-time on the business now, spending most of the year preparing for the summer rush when demand skyrockets. Two years ago, when her social media presence took off, she was working until three in the morning alongside her father just to keep up with orders. "It is a very chaotic, busy time," she said. "The demand goes up every year so I am up most nights working and that's my life for a few months."

For the students themselves, the process has become part of the ritual. Aarushi, a fifteen-year-old GCSE student from Warwickshire, is planning a Guardians of the Galaxy-themed shirt and describes the design work as a welcome break from exam stress. She's been scrolling through Pinterest for ideas and plans to invite friends over to create designs together, turning it into a social event rather than a solitary task. "There's definitely a pressure to have a good shirt and choose the right design," she acknowledged, "but it's a good memory as it's your last day of secondary school." She's also hopeful that the shirts will spark new connections: "I can't wait to see other people's designs at school, you can spot similar personalities with similar shirts and that could spark new friendships."

The shift from the old tradition—signing shoes, hoodies, and yearbooks—reflects something deeper about how young people want to mark their transitions. Some schools have even begun running competitions to see who has the boldest design, turning leavers' day into an unofficial fashion show. What began as a way to preserve memories has become a statement of identity, a final declaration of who you are before moving on. The shirt sits at the intersection of nostalgia and self-expression, permanence and creativity. It's a keepsake that won't fade like pen on fabric, and it carries the weight of an entire chapter of life.

The shirt is a physical memory, a reminder of fun with all your feelings and nostalgia.

Why do you think this particular tradition took off now, rather than five or ten years ago?

Model

Social media changed everything. Before TikTok and Pinterest, you didn't see what other schools were doing. Now a video of a hand-painted shirt can reach millions of people in days. It made the idea feel possible and desirable at the same time.

Inventor

Is there something about the permanence that matters? Why not just sign a regular shirt?

Model

A regular shirt fades. The ink runs, the fabric tears. This is different—it's meant to last. And because it's custom, it feels like it belongs to you in a way a blank shirt never could. It's not just a memory holder; it's a statement.

Inventor

Do you think there's real pressure behind this, or is it genuinely fun?

Model

Both. Aarushi said it herself—there's pressure to have a good design, to go bigger and bolder than everyone else. But that pressure exists alongside genuine creativity. The best part is when friends gather to design together. That's when it stops being about competition and becomes about connection.

Inventor

What happens to these shirts after leavers' day?

Model

They get kept. People hold onto them for years. It's one of the few school traditions that actually becomes a permanent artifact of who you were at sixteen. That's why the entrepreneurs can charge £35 a shirt. Students understand they're buying something they'll treasure.

Inventor

Does this trend say anything about how teenagers see themselves?

Model

It says they're hungry for permission to be themselves. Joy Nzau noticed that—students are more willing to express who they actually are at the end of term than they are during the school year. The shirt becomes proof that individuality is acceptable.
