It started with a jingle. Back in the 1970s, the Nair commercial asked the world a simple question, and for decades, the answer was almost exclusively marketed to women. But walk through a park today or scroll through any social media feed, and you'll see the tide has turned. It’s the guys.
The "5-inch inseam" isn't just a measurement anymore; it’s a cultural movement.
Honestly, the shift from baggy, below-the-knee cargo shorts to mid-thigh territory has been one of the most aggressive pivots in men's style since the skinny jean died a slow, painful death. We’re talking about a complete overhaul of the male silhouette. For years, men were hiding. They were drowning in fabric. Now? They're showing quad.
The Viral Rise of the 5-Inch Inseam
If you want to know who wears short shorts today, look no further than TikTok's "Hoochie Daddy Season." It sounds ridiculous because it kind of is, but the trend has serious legs—literally. What started as a joke about men reclaiming their right to be "scandalous" turned into a massive retail shift. Brands like Chubbies and Bearbottom built entire empires on the idea that 7 inches was too long and 9 inches was basically a pair of trousers.
Fashion historians often point to the 1970s as the golden era. Think of Larry Bird on the basketball court or Tom Selleck in Magnum, P.I. Those shorts were short. They were functional. They allowed for movement. Then, the 1990s hit. Michael Jordan and the "Fab Five" at Michigan pushed the hemline down, and suddenly, showing your knees was a fashion crime.
We stayed in that baggy purgatory for twenty years.
But trends are cyclical. The pendulum swung back so hard it almost hit us in the chin. Paul Mescal, the actor known for Normal People, became a poster child for the movement simply by going for a jog in vintage-style GAA shorts. The internet didn't just notice; it obsessed. People realized that the shorter cut actually makes men look taller and more athletic. It’s a proportional trick. When you cut off the visual line at the mid-thigh instead of the knee, your legs look longer.

High Fashion Meets the Street
It’s not just about influencers and gym rats. High-end designers have been pushing this on the runway for several seasons. Prada’s Spring/Summer collections have featured "skort-like" ultra-shorts that make the 5-inch inseam look conservative.
Miuccia Prada and Raf Simons aren't doing this by accident. They’re tapping into a broader move toward gender-fluid dressing and a rejection of the rigid, "tough guy" aesthetic of the early 2000s. There’s a certain confidence required to wear a 3-inch inseam. It says you don't care about traditional modesty.
You’ve probably noticed this at the gym too. Crossfitters and weightlifters were the early adopters. When you’re doing squats, excess fabric is an enemy. It bunches. It catches on the bar. Performance-wear brands like Lululemon and Gymshark saw the data and started shrinking their standard offerings. Now, the 5-inch is the bestseller, and the 7-inch is the "safe" choice for people who aren't quite ready to commit.
Why the Change Actually Happened
- The Thigh-Brow Trend: Social media loves a "reveal." Short shorts create a visual interest point that baggy shorts just can't match.
- Body Positivity for Men: There’s a growing culture around leg day. If you’ve spent six months working on your teardrop muscles (the vastus medialis), you aren't going to hide them under ten inches of heavy denim.
- Heat Waves: Let’s be real. It’s getting hotter. Practicality wins.
- Vintage Revival: Thrifting is huge. People are finding old 80s gym shorts and realizing they look better than modern mall brands.
Who Wears Short Shorts Better? The Great Debate
There is still a lot of gatekeeping. Some people think anything above the knee is "too much." But if you look at the history of the garment, the long-shorts era was actually the anomaly. Throughout most of human history, if men wore shorts, they were short.
Look at the Australian "stubbie" shorts. They never left. In Australia, the short-short has been a blue-collar staple for decades. It’s workwear. It’s rugged. It’s funny how a garment can be seen as "effeminate" in one culture and "hyper-masculine" in another.
The real experts in this space—people like fashion editor Derek Guy—often talk about balance. If you're going short on the bottom, you usually want something a bit more substantial on top. A 5-inch inseam paired with a tight tank top can look like you’re heading to a 1982 bodybuilding competition. But that same pair of shorts with an oversized linen button-down? That’s a classic summer look.

The Physics of the Inseam
Let's break down the measurements because most guys get this wrong.
The inseam is measured from the crotch to the bottom of the leg opening. A 9-inch inseam will usually hit right at the top of the kneecap for an average-height man. A 7-inch inseam shows a bit of thigh. A 5-inch inseam is the "sweet spot" for the current trend. Anything 3 inches or below is entering "marathon runner" territory.
Materials matter here too. Denim short shorts—often called "jorts"—are making a comeback, but they have zero stretch. This is dangerous territory. If you’re going short and tight in a non-stretch fabric, you’re going to have a bad time when you try to sit down. This is why most of the who wears short shorts crowd sticks to nylon blends or "tech" fabrics.
Cultural Impact and "The Jingle"
We can't talk about this without mentioning the 1980 Nair commercial. "Who wears short shorts? We wear short shorts!" It was an anthem for hair removal. For a long time, that jingle tied short shorts to a very specific feminine beauty standard.
Breaking that association took time. It took the 2010s "prep" revival (think Vineyard Vines) to start shortening the hemlines, and then the 2020s "indie-sleaze" and fitness culture to finish the job. Today, the gender barrier on leg length has basically vanished.
Actionable Tips for Transitioning to Shorter Shorts
If you’ve been wearing knee-length cargo shorts since 2004, jumping straight to a 5-inch inseam might feel like you’re walking around in your underwear. It’s a psychological hurdle.

Start with the 7-inch rule. This is the gateway drug of shorts. It’s undeniably modern but doesn’t feel "risky." It shows you have a sense of style without forcing you to explain your outfit to your more conservative relatives at the family BBQ.
Watch your footwear. Proportions are everything. Short shorts with massive, chunky basketball shoes can make your legs look like toothpicks. Try a slimmer profile like a Vans Authentic, a Sperry boat shoe, or a classic white leather sneaker like a Common Projects Achilles (or a more affordable alternative).
Check the leg opening. The biggest mistake guys make isn't the length—it's the width. If the leg opening is too wide, a short short will flare out like a skirt. You want something that follows the line of your leg without being skin-tight.
Confidence is the secret ingredient. The reason why celebrities like Milo Ventimiglia or Donald Glover look good in short shorts isn't just their physique. It’s the fact that they don’t look like they’re constantly trying to pull them down. Own the look.
The "Who Wears Short Shorts" era isn't a passing fad. It’s a return to form. We are moving away from the era of "hiding" our bodies under layers of excess fabric and moving toward a more functional, expressive way of dressing. Whether it's for the gym, the beach, or just grabbing a coffee, the hemline has moved up, and it’s likely staying there for the foreseeable future.
Practical Next Steps
- Measure your favorite pair: Find the shorts you currently feel best in and measure the inseam. If it's 9 inches, buy your next pair at 7 inches.
- Focus on the rise: Shorter shorts look better with a mid-to-high rise. If they sit too low on the hips, the proportions will look "off."
- Fabric choice: For your first pair of 5-inch shorts, go with a matte nylon or a heavy cotton twill. Avoid shiny athletic fabrics unless you're actually at the gym.
- The "Sit Test": Always sit down in the dressing room. Shorter shorts ride up. Make sure you’re comfortable with how much skin is showing when you’re seated before you commit to the purchase.
The trend is here. The knees are out. It's time to adjust the wardrobe accordingly.
