Classic / Regular Fit The gold standard. Not too tight, not too baggy. Classic fit T-shirts give you room to breathe without looking sloppy. If you're unsure where to start, start here.
Slim Fit Tailored closer to the body without hugging it like a second skin. Great if you’ve got a lean build and want to show it subtly—not scream it.
Athletic Fit Made for V-shaped guys. Trim through the waist but with extra room in the chest and shoulders. It’s like a slim fit that lifts weights.
Muscle Fit This one’s tight. Really tight. Think spray-on sleeves. If you’ve put in the work at the gym and want the shirt to prove it for you, this is your cut.
Relaxed Fit A little looser than regular. Gives you extra room without drifting into oversized territory. Perfect for lounging or layering.
Oversized Fit Longer sleeves, wider body, dropped shoulders. Popular in streetwear and ideal if you're going for an intentionally baggy look.
Boxy Fit Short and wide—like a cropped classic. Inspired by vintage tees, this cut gives off a laid-back, retro vibe.
Tall Fit Built with longer torsos in mind. Same proportions as regular, but with added length to avoid midriff exposure (aka the dreaded “crop top effect” for tall guys).
T-Shirt Fit & Formality: From Smart to Ultra Casual
Not all T-shirts are created equal—especially when it comes to how formal or casual they look. The fit of your T-shirt plays a huge role in how polished—or relaxed—you appear.
A slim or classic fit can come off sharp and intentional, especially when paired with the right outfit, while relaxed, oversized, or boxy fits push the vibe into ultra-casual territory.
Athletic and tall fits sit somewhere in the middle, giving you flexibility depending on how you style them. Use the guide below to see where each fit lands on the smart-to-casual spectrum.
Neckline Styles (Can Apply to Any Fit)
Crew Neck Simple, timeless, and universally flattering. This round neckline is the default for most T-shirts—and for good reason.
V-Neck Opens up the neck area slightly, elongating your look. Especially helpful for shorter guys or guys with rounder faces.
Henley A crew neck with 2–5 buttons. Adds a touch of rugged masculinity and visual interest without trying too hard.
Scoop Neck Similar to a crew but with a deeper dip. More relaxed and casual—sometimes even a bit edgy, depending on the outfit.
Mock Neck A high collar that sits close to the neck, but doesn’t fold over. Think turtleneck vibes without the commitment.
Boat Neck A wide, horizontal neckline that reaches closer to the shoulders. Originated in French naval uniforms—perfect for minimalist or artsy styles.
Deep V-Neck A bold, plunging neckline that shows off more chest than a standard V. Popular in fashion-forward or fitness-focused looks, it gives off a confident, edgy vibe—best worn when you're aiming to stand out.
T-Shirt Necklines & Formality: Small Detail, Big Impact
Neckline style might seem like a small design choice, but it can shift your entire look from polished to laid-back.
Crew necks and mock necks tend to lean more refined and structured, while scoop necks, Henleys, and boat necks give off a more relaxed, casual feel.
Turtlenecks, although technically still tees, can even edge into smart-casual territory when paired right. Use the neckline guide below to get a sense of how each style fits into the formality spectrum—and choose what works best for your vibe.
Sleeve Lengths (Can Apply to Any Fit or Neckline)
Short Sleeve The classic. Ends around the middle of your biceps. Easy, versatile, and works with basically any outfit.
Long Sleeve More coverage, more layering potential. Can be casual or slightly more elevated depending on fabric and fit.
Three-Quarter Sleeve Hits between the elbow and wrist. Think baseball-style tees. Great transitional piece for unpredictable weather.
Cap Sleeve Covers just the top of your shoulder. Most often seen in fashion-forward or fitted styles—less common in standard men’s tees.
Raglan Sleeve The shoulder seam runs diagonally from the collarbone to the underarm. Often used in sporty or athletic designs. Bonus: visually broadens the shoulders.
T-Shirt Sleeve Length & Formality
Sleeve length might seem like a basic feature—but it can say a lot about how polished (or relaxed) you look.
Short sleeves are the classic go-to and generally sit in the middle of the formality scale, especially when they hit around mid-bicep. Go longer, and you start drifting into a more laid-back, oversized vibe.
Cap sleeves or rolled sleeves feel trendier and more casual, while 3/4 and long sleeves (like in raglans or baseball tees) can add a hint of structure or intentional style.
Hem Styles
Straight Hem The default option—clean and even all the way around. Works for tucking in or leaving out.
Curved Hem The bottom edge curves slightly, giving a softer silhouette. Adds subtle style points without standing out too much.
Drop Tail Hem Longer in the back than the front. Designed to cover your backside—especially helpful for taller guys or activewear styles.
Scallop Hem A more dramatic curve with added length. Often used in streetwear. Looks great layered under a shorter jacket or hoodie.
Split Hem Little side slits at the bottom. Not only adds interest but makes movement easier—especially useful in oversized or longer cuts.
T-Shirt Hem Style & Formality
Hem style is one of those under-the-radar details that quietly shifts how dressed-up—or down—you look.
A straight hem delivers that classic, casual finish most common in everyday tees. It’s relaxed, balanced, and easy to wear untucked.
A curved hem, on the other hand, adds visual interest and leans more modern. It can elongate your frame and create a slightly more polished silhouette—great for smart-casual looks.
Split hems (with side slits) suggest intentional styling and add movement. While still casual, they elevate the shirt subtly and work well layered under jackets or overshirts.
Scallop hems—rounded with a longer back—add flair and function. They’re a trendy upgrade that works great for layering and offer a more tailored, intentional vibe.
Drop-tail hems extend the back even further. Originally designed for coverage during movement (like in streetwear or athletic fits), they read very casual and lean heavily fashion-forward.
Edge Hemming
Raw Edge / Plain Cut No stitching at the edge—just fabric cut cleanly. Has a rugged or deconstructed vibe, but can fray over time if not treated.
Frayed Edge A deliberately worn-in look. Threads are loose or unraveling on purpose. More style than function.
Self-Fabric Bands The edge is finished with a strip of the same material. Common around necklines and sleeves—gives a uniform, clean look.
Overlocked / Serged A commercial finish where threads are looped over the edge. Prevents fraying and looks professional, especially on inner seams.
Ringer Style Contrasting color fabric bands sewn onto the collar and sleeves. Vintage feel, instantly recognizable.
Blind Stitch Almost invisible from the outside. Used to create a very clean, minimal look.
Single Stitch One row of stitching. Found in vintage tees—if you're thrifting and see this, you may have a gem.
Double Stitch Two visible lines of stitching. Strong, durable, and the most common commercial finish for hems.
T-Shirt Edge Hemming & Formality
The way your t-shirt edges are finished can quietly define how formal—or ultra casual—your look feels.
At the smarter end of the spectrum, self-fabric bands and blind stitches offer a clean, elevated finish. These are often seen in high-quality tees designed for layering or smart-casual looks.
Single- and double-stitched hems are your everyday essentials—structured, durable, and appropriate for most casual outfits. Double stitching adds visual weight and durability, while single stitch gives off a more vintage, minimalist vibe.
Going more relaxed? Rolled stitches, ringer styles, and overlocked edges start to feel sportier and more playful. These work well for laid-back weekends or creative streetwear.
At the far casual end, raw edges, plain cuts, and frayed hems bring edge and rebellion—but they can also make you look careless if not styled intentionally.
The rule? Clean edges signal polish. Raw finishes say, “I’m not trying too hard.” Choose your hem like you choose your shoes—based on where you’re going and how you want to show up.
T-Shirt Colors: What They Say & How to Choose
Color might seem like a small detail, but it can make or break a look. The right T-shirt color can boost your complexion, bring out your eyes, and subtly communicate your vibe. The wrong color? It can wash you out or make you look tired.
Let’s break down the common color groups—and then I’ll show you how to pick the right ones for your skin tone.
Neutral Colors

White brightens your look—great for summer or under jackets.
Black is slimming, sleek, and works for almost every situation.
Gray is balanced—dress it up or down.

Beige/tan adds warmth and works well with denim or olive.
Why they're great: They stand out and make a statement. Perfect if you want attention or to show some personality.

Keep the rest of your outfit simple to avoid clashing.

Why they're great: Soft, modern, and a bit preppy. They feel fresh and clean, especially in warmer weather.

Pair with white jeans, khakis, or light wash denim for a clean look.
How to Choose the Right T-Shirt Color for Your Skin Tone
Knowing your skin’s undertone is key. You don’t need to overthink it—just follow these quick tips:
Cool Undertones
(Your veins look blue; silver jewelry looks better than gold)
Best Colors:
Navy, charcoal, crisp white
Cool pastels: lavender, light blue
Jewel tones: emerald, sapphire, burgundy
Avoid: Yellow-heavy tones like mustard or most beige shades—they can make you look pale.
Warm Undertones
(Your veins look green; gold jewelry looks better than silver)
Best Colors:
Earth tones: olive, rust, mustard, tan
Warm neutrals: cream, beige, brown
Soft warm colors: coral, peach, warm reds
Avoid: Icy blues or super cool grays—they may look harsh against your skin.
Neutral Undertones
(You’re not clearly warm or cool)
Best Colors:
You get the best of both worlds!
Stick to mid-tones: teal, jade, true red, stone, mid-gray
Try layering to play with both warm and cool tones
Quick & Dirty Color Tips:
When in doubt, navy, gray, and olive work on everyone.
Want to look more tan? Try white or pastel tones.
Looking for something slimming or sleek? Black and dark tones are your friend.
Need to add energy to your outfit? Brights or bold mid-tones will do the trick.
T-Shirt Fabrics: What You’re Really Wearing (And Why It Matters)
Most guys only think about the fit or the color of their T-shirt—but the fabric is what truly decides how it feels, how it looks, and how long it lasts.
If you’ve ever wondered why one tee feels like pajamas and another like sandpaper, here’s your answer.
Cotton
The king of T-shirt fabrics. Breathable, soft, and natural. It’s what most T-shirts are made from—and for good reason.
Pros: Comfortable, easy to care for, versatile.
Cons: Can shrink, wrinkle, and fade over time (especially cheaper cotton).
Best for: Everyday wear, layering, and classic looks.
Tip: Look for “combed cotton” or “ringspun cotton” if you want something softer and more durable.
Cotton Blends (Usually with Polyester)
A modern update to classic cotton. Usually 60/40 or 50/50 cotton/poly.
Pros: Less shrinkage, more wrinkle-resistant, dries faster.
Cons: Less breathable than pure cotton, can feel slightly “slick” or synthetic.
Best for: Athleisure, travel, and low-maintenance wardrobes.
Tip: If you want a shirt that lasts through the wash and still looks good—this is your friend.
Tri-Blend (Cotton + Polyester + Rayon)
Soft, stretchy, and lightweight—almost like a vintage tee from day one.
