The evolution of the T-Shirt

It’s a wardrobe staple so ubiquitous and basic that it’s surprising to even think of it as having been “invented”.

But the humble t-shirt is a relatively recent innovation, and it its possible to trace  its evolution from undergarment to outerwear.

Loose-fitting, t-shaped garments worn as underwear date back to the Middle Ages, but the history of the t-shirt as we know it today began in  the 1800s, when jumpsuits and long johns began being adapted for comfort. Sailors and laborers were known to cut jumpsuits in half to stay cool, and the practical pieces caught on. By 1898, t-shirts were beginning to be manufactured on an industrial scale.

In the early 20th century, the Cooper Underwear Company (now “Jockey”) marketed t-shirts as a convenient wardrobe staple for bachelors who couldn’t sew on buttons.  Also taking note of their practicality, the US Navy began issuing them as standard undershirts in 1913.

It is believed that the first time the word “t-shirt” appeared in published writing was in F Scott Fitzgerald’s novel, This Side of Paradise. It was added to the Merriam-Webster dictionary in 1920. Later on  in the 20s, when central heating was widely introduced to homes, undershirts that were usually made of wool started being made of cotton.

T-shirts remained an undergarment until after the Second World War. In the 1940s, veterans popularized the look of a plain t-shirt worn with trousers or jeans, and high-schoolers were quick to emulate the style. In the 1950s, two iconic film roles catapulted the “t-shirt as outerwear” look to stardom- Marlon Brando as Stanley Kowalski in A Streetcar Named Desire (1950), followed by James Dean in Rebel Without a Cause (1955). Both protagonists wore fitted white t-shirts, looks that remain iconic to this day.

These moments captured the spirit of a brewing rebellious, counter-cultural moment, and it didn’t take long for t-shirts to be emblazoned with decorations, designs, and- importantly- slogans.

(The first “slogan T-shirt” is attributed to presidential candidate Thomas E Dewey, who distributed shirts reading “Do it With Dewey”).

The 1960s brought the invention of plastisol ink, which allowed for easy screen-printing and dyeing. T-shirts became billboards for activist slogans, rock band logos,  and any other form of self expression. 

Today, over ninety-five percent of Americans are t-shirt wearers. Of those, 87% report having at least one t-shirt they are keeping solely for sentimental reasons. 

 

What’s your name and what do you do in life? Tell us about yourself and your business!
I’m Emily LaPlume, Founder & CEO of Saturday Swimwear — a sustainable women’s swimwear brand designed for real life and real bodies. I’m passionate about creating timeless, comfortable, and eco-conscious swimwear that’s made ethically right here in the U.S.

What inspired you to get into your field of work?
Saturday Swimwear was born from my own frustration trying to find a swimsuit that felt good, looked good, and was functional. My shift towards sustainability came after witnessing the first hand effects fast fashion and overconsumption were having on the environment and developing communities around the world. I set out to prove that you don’t have to compromise between style, comfort, or responsibility. What sets us apart is that we manufacture small batch collections in Los Angeles, use sustainable fabrics like ECONYL® regenerated nylon, and prioritize quality, fit, and function — creating suits that move with you, not against you.

Tell us about a milestone in your work or something that you’re especially proud of!
In 2022, I started what I call my “Artist Series,” where I collaborate with a female-identifying designer to create a one of a kind print for our suits inspired by their connection with nature. It has allowed me to connect with other creatives and tell the store behind the print, encouraging customers to build an even deeper connection with the products they’re purchasing. While it is taking a hiatus for 2025, we are working on some fun stuff for next year!

What inspires you? Where do you look for inspiration?
Nature is my biggest source of inspiration — especially the landscapes of the Pacific Northwest. From the muted tones of a misty coastline to the vibrant colors of alpine wildflowers, I pull a lot of ideas for color palettes, textures, and even product design from time spent outdoors.

Do you know any resources for textile recycling?
A great option available right here in Portland is Ridwell. There is also For Days’ “Take Back Bag” program and Terracycle. Some cities have their own textile-specific recycling drop-offs!

Tell us your favorite secondhand shopping story?
My husband and I recently moved to Portland and during our first day exploring our new neighborhood, we discovered Consign Couture and I was SHOCKED at how well curated and not overwhelming CC felt (I will be the first to admit that secondhand shopping can feel fairly overwhelming for me). I found a pair of pants and shoes that I loved, but ultimately decided to hold off on buying them. The next day, my husband had gone back and purchased both items and surprised me with them for my birthday.

What challenges have you encountered while working to make Saturday Swim more environmentally sustainable? How have you addressed them?
Sustainability is at the core of Saturday Swimwear — from sourcing recycled materials to producing in small batches to minimize waste. One challenge is that eco-friendly fabrics and ethical manufacturing cost significantly more, which can make it harder to compete with fast fashion brands. But I’ve found that our customers want to invest in products that they know will last, align with their values, and fit well.

Tell us about your favorite outfit. What makes you feel your best, or the most “you”?
My go-to is a pair of dark grey straight denim jeans from Whimsy + Row, a black ribbed, cropped tank from Pepper, a thrifted, vintage Palmetto’s Fleece jacket, and my Blundstones. Despite working in the fashion industry, I love simplicity and most of my clothes are grey, black, or forest green.

What do you do in your free time?
You can usually find me outside — hiking, snowboarding, walking my dogs, or camping. I have recently rediscovered my love for reading and can always get down with a good book and a hammock hang.

Three things: The best thing you’ve read, the best thing you’ve watched or listened to, and the best thing you’ve eaten lately?
Read: I’ve been on a serious fantasy kick and just finished Crescent City by Sarah J. Maas.

Eaten: Having just moved to Portland, it is hard to choose one thing, but we have been loving the croissants from Baker & Spice in Hillsdale!
