From Casual to Put-Together: A Guy’s Guide to Great Knitwear
By Brandi Hearn, Personal Stylist for Men
There’s nothing like a good sweater—one that fits just right, feels like a hug, and makes you look like you actually planned your outfit (even if you didn’t).
But here’s the thing:
Most men are wearing the wrong style, the wrong fit, or something that’s way past its prime.
This guide will help you build a lineup of sweaters, cardigans, and sweatshirts that not only keep you warm—but also keep you looking put-together no matter where you’re headed.
Why They Matter
Yes, they’re practical. Yes, they’re comfortable.
But more than that, sweaters and sweatshirts are quiet style upgrades.
They add structure, texture, and personality—without requiring a second thought.
Whether you’re dressing for the office, a date, or a Sunday grocery run, they’ve got you covered.
Let’s Start with the Common Mistakes
The goal here isn’t to shame anyone—just to help you do better.
Sweaters
Crewnecks over dress shirts? Doesn’t work. Stick with tees underneath.
V-necks over t-shirts or bare skin? Skip it. These are made for collared dress shirts.
Too tight or too loose: You want something that skims your shape—not clings or drowns you.
Worn out fabrics: If it’s severely pilled, hole-y, or thinning, it’s time to let go. (Even if it’s comfy.)
Cardigans
Bright colors: Unless you’re Mister Rogers, keep it neutral.
Layering shawl collar cardigans under jackets: These are your outer layer, not an undershirt.
Wearing them buttoned up when you’re broader in the middle: It’s not flattering. Wear them open and let the layers do the work.
Sweatshirts & Hoodies
Loud graphics or big logos: These don’t read as stylish. They read as teenage.
Trying to hide your midsection with bulk: Unfortunately, this has the opposite effect.
Workout fabrics in casual outfits: If it shines, skip it—unless you're at the gym.
Your Sweater Options (And When to Wear Them)
Crewneck Sweater
A true essential. Throw it over a crewneck tee for casual days or under a jacket when you want to look more polished.
V-Neck Sweater
This one leans dressier. Perfect for layering over a collared shirt—especially if you’re headed into the office or a meeting.
Cardigan
Like a casual blazer, but softer and more forgiving. Great for layering and for days when you want to look pulled together without going full button-down.
Shawl Collar Cardigan
This is your cozy hero piece. Think of it as a knit jacket—something that looks great on its own, especially when worn open.
Sweatshirt
Soft, classic, unfussy. Ideal for everyday looks. Pair with jeans or joggers, and you’re set.
Hoodie
Wear it clean and simple. Avoid anything flashy, and layer it under a casual jacket if you want to dress it up just a bit.
Optional—but Worth Considering
Turtlenecks: A cool-weather upgrade. Just don’t let it swallow your neck.
Quarter-Zips: A good option if you’re in your late 30s or beyond. Anything higher than a quarter zip? Feels dated.
Cable-Knits: Great texture, great presence. Let them be the statement piece.
Long-Sleeve Polos: Heavier weight, casual vibe. Not for dressing up, but perfect with denim.
Fabric Tips (So You Don’t Regret the Purchase)
Sweaters & Cardigans:
Cashmere: Soft and luxe, but delicate.
Merino Wool: Lightweight and breathable.
Regular Wool: Warm, classic, durable.
Cotton: Easy-care, budget-friendly.
Blends: Great if you run warm or want a lighter layer.
Sweatshirts & Hoodies:
Stick to cotton or a cotton blend with minimal synthetic shine. You want structure and softness, not something that looks like gym gear.
Go-To Colors That Just Work
Sweaters & Cardigans:
Black: Timeless and versatile.
Navy: Clean, classic, pairs with almost anything.
Charcoal: The underrated MVP—goes with nearly every neutral.
Sweatshirts & Hoodies:
Heather Gray: Works on every skin tone and feels fresh.
Charcoal/Black: Clean, low-maintenance, and easy to match.
Fit—The Details That Make the Difference
Sweaters & Cardigans
Shoulder seams line up with the end of your shoulders.
Sleeves stop right at your wrist—no bunching.
Snug (not tight) at the arms and torso.
The hem should hit just below the belt.
Sweatshirts & Hoodies
Same fit rules apply: tailored through the body and arms, but comfortable.
If it’s “relaxed,” keep the rest of the outfit structured so you don’t look sloppy.
