International T-Shirt Day is on June 21, and tees are anything but basic. From viral slogan shirts to oversized fits, here&rsquo;s how to style your T-shirt for any occasion with on-trend flair.

Talk the Talk: Slogan Tees

Attending a Hollywood movie premiere in a bold slogan T-shirt under a coat? In 2025, it&rsquo;s not only acceptable, it&rsquo;s a power move. Slogan tees are absolutely everywhere this year, resurrecting the era of the statement T-shirt and taking it to new heights. Some designs tap into nostalgia &ndash; for instance, Dior brought back the classic &ldquo;J&rsquo;adore Dior&rdquo; slogan top for Autumn/Winter 2025, giving Y2K fans a thrill. Others carry timely messages: London designer Conner Ives&rsquo;s &ldquo;Protect The Dolls&rdquo; T-shirt supporting trans women has exploded in popularity, spotted on celebrities from red carpets to music festivals. The beauty of a viral slogan tee is that it speaks for you &ndash; literally. Style one with your go-to denim and let the bold lettering become the focal point of your casual look, or clash the casual with the chic by layering a slogan tee under a sharp suit jacket. Whether you choose a tee with an ironic meme, a political statement, or just a funny saying, wear it proudly. In 2025, your chest doubles as your social feed, broadcasting your personality and convictions in the coolest way.

Collaboration Craze

If fashion has a motto, it&rsquo;s &ldquo;collaboration is king.&rdquo; Designers and brands are teaming up and it feels like there&rsquo;s a buzzy new collab drop every week. These limited-edition T-shirts often feature exclusive art, logos, or pop-culture mashups that turn a simple tee into a collector&rsquo;s item. Wearing a collab tee is the ultimate flex for the in-the-know fashion crowd, whether it&rsquo;s a luxury streetwear partnership or a high-street designer capsule. To rock a collab T-shirt, let it shine as the outfit&rsquo;s centerpiece: pair it with neutral cargo pants or classic jeans so the bold design pops, and throw on your favorite sneakers. For a twist, you can also dress up a logo-laden collab tee with a sleek blazer and trousers &ndash; high-low fashion at its finest. After all, these tees come with built-in clout, so wear them with confidence and let the shirt do the talking.

Oversized: Go Big or Go Home

Baggy, boxy, and utterly comfy &ndash; oversized T-shirts continue to reign in 2025, drawing inspiration from &rsquo;90s hip-hop and skater style. Gen Z&rsquo;s love of all things loose. The appeal is obvious: an oversized tee gives you instant streetwear cred and a laid-back, &ldquo;I woke up like this&rdquo; effortlessness. To keep your XXL shirt looking intentionally stylish (and not like you raided your dad&rsquo;s closet by accident), balance is key. Try tucking in just the front of an oversized tee into high-waisted jeans or shorts to give your outfit some shape, or throw on a fitted bomber or denim jacket over it to structure the volume. You can play with proportions by pairing an extra-long tee with bike shorts or leggings &ndash; a favorite off-duty model combo &ndash; flashing a bit of leg so the look is relaxed yet figure-flattering. For a full streetwear vibe, style an oversized graphic tee with baggy cargo pants or joggers and finish with chunky &ldquo;dad&rdquo; sneakers and a cap. The result? A chef&rsquo;s kiss blend of comfort and cool. Whether you&rsquo;re running errands, hitting a concert, or just lounging, oversized tees prove that sometimes, bigger is better.

Throwback Tee: The Charm of Nostalgia

Everything old is new again &ndash; especially when it comes to T-shirt graphics. Nostalgia and sentimental charm are influencing T-shirt designs in a big way. Have a band tee from a 2003 tour? A shirt with your favorite childhood cartoon or a vintage sports team logo? Now&rsquo;s the time to proudly put it back in rotation. Fashion fans have been drooling over nostalgia: faded rock band tees, bold retro logos, tie-dye, and anime graphics are all back. To style a nostalgic print tee, you can fully embrace the throwback. Toss on some high-waisted light-wash mom jeans and classic sneakers, and maybe add a scrunchie or bucket hat as a tongue-in-cheek nod to the era. Alternatively, mix decades by pairing a vintage-look graphic T-shirt with contemporary pieces, layer a blazer on top, or wear it with a modern midi-skirt and boots, blending old-school and new-school. Wearing a print that sparks memories will not only earn style points but also serve as a great conversation starter &ndash; &ldquo;omg, I had that same Pok&eacute;mon shirt in fourth grade!&rdquo; That&rsquo;s the magic of the throwback tee.

Second-Skin Energy

Not all T-shirts need to be baggy to be cool. Skin-tight tees are making a major comeback, especially in contrast to the oversized everything trend. Think stretchy, form-hugging fits that feel sleek and a little bit sultry. They're minimalist, but never boring.

The Classic White Tee

Sometimes the loudest move is keeping things quiet. A plain white T-shirt is the wardrobe MVP, clean, crisp, and endlessly versatile. It works with literally everything, whether you're feeling minimal or in the mood to layer. The best part? A good white tee makes your entire outfit feel intentional, even when you're running late.
