How to Dress in Your 30s (and Look Sharp)

What should a sharp 30-something wardrobe look like? When mapping out how to dress in your 30s, a man needs to leave behind his 20s outfits and dress with intention.

Dressing well in your 30s matters a lot more than it did in your 20s. Now it's about focusing on fit, color, fabric, and accessories — it's about buying smarter, not spending more.

If you're curious about the style fundamentals of 30s attire and are ready to upgrade your wardrobe with key essentials, this definitive guide is for you. We clearly steer you through what to leave behind, what to invest in, and the fundamentals that make it all work. Then we wrap it all up with how to dress for specific situations you actually encounter in your 30s. 

What to Leave Behind From Your 20s

Upgrading your style in your 30s isn't always about buying new things. It's about giving up pieces that don't actually work now. Clean out your closet and purge:

• Graphic tees
  
• Distressed or overly light-wash jeans
  
• Baggy or oversized hoodies
  
• Sneakers as everyday footwear
  
• Oversized cargo shorts and cargo pants
  
• Anything with a visible logo across the chest
  

The Style Fundamentals: Fit, Color, and Fabric

No wardrobe upgrade will work if the fundamentals are wrong. The style fundamentals of fit, color, and fabric separate a 30-something who looks pulled-together from a guy who owns nice pieces but wears them poorly. Master these three style fundamentals:

• Fit: Proper fit is everything. Even the costliest pieces will fall flat if they don't fit your frame correctly. 
  
• Color: Follow the 3-Color Rule. For a cohesive and balanced look, an outfit should have three colors: a dominant, a secondary, and an accent color. 
  
• 60% should be the dominant or base color. 
  
• 30% should be a color that supports and complements the dominant color. 
  
• 10% should be an accent color that provides visual interest.
• Avoid colors that fight each other. Clashing colors are distasteful and detract from an intentional look. If you're unsure about color coordination, take a look at the principles of color theory.
• Fabric: The fabrics you choose matter more in your 30s than they did in your 20s. Fabric dictates fit and how a garment drapes on your body.
• Seek out fabrics that look neat and smooth, not bunched and stretched. High-grade natural fabrics like wool, linen, and cotton are preferable for their comfort, appearance, and their durability.
  

Wardrobe Essentials Every Man in His 30s Should Own

How to dress as a man in your 30s isn't about a vast wardrobe. Owning fewer higher-quality pieces always beats a closet full of mediocre clothing.

Jackets and Outerwear

Core jackets and outerwear pieces include blazers, sport coats, wool overcoats, and bomber  or chore jackets. A well-fitted blazer is the single most versatile piece a 30-something can own. 

Fit is essential and much more important than brand or cost. Consult our comprehensive jacket size guide for details on how to achieve the right fit for your jackets and outerwear.

Shirts and Knitwear

Fit, fabric, and color! The fundamentals definitely apply when selecting shirts. The best way to get the most out of your dress shirts is to establish a small rotation of high-quality pieces in white, light blue, and a few subtle patterns. 

Add short sleeve polos for warm weather. Long-sleeve polos and fine-knit merino sweaters are terrific for cool and cold weather layering.

Your shirts should fit through the shoulders and chest without pulling. Our shirt measurement chart and dress shirt size guide will help you find the perfect torso, shoulder, sleeve, and collar fit.

Pants and Trousers

Stock your wardrobe with a mix of dark-wash jeans, chinos, and wool trousers. Avoid relying on a single pant style. The "jeans every day" habit is one of the most obvious markers of an under-developed wardrobe.

Flat-front or single pleat trousers in straight or slim-fit cuts and clean lines are most current. The trend for tight-fit skinny jeans and baggy pants has passed.

Footwear

Three essential footwear styles will go with everything in your wardrobe and take you just about anywhere. Leather sneakers are great for casual wear. Wear suede or leather loafers, monk straps, or Chelsea boots for a dressier look. Dark derbies, Oxfords, or dress boots are worn for formal occasions. Avoid the corporate shiny black dress shoe look.

Only wear shoes that are in good condition and well-maintained. Leather shoes should be polished. At this point in your life, matching your belt color to your shoe color is a basic sartorial rule you should follow. Matching leathers creates an outfit that looks intentional and cohesive.

Accessories That Signal Maturity

Accessorizing is one of the fastest and most affordable ways for a man entering his 30s to level up his wardrobe. If you're focusing on how to dress in your late 30s a man should definitely rely on the power of accessories:

• Ties – From casual knits to formal solid silk ties, add a necktie to your outfit to create polish, sophistication, and balance.
  
• Pocket squares – With or without a tie, accessorizing with pocket squares provides style and interest. 
  
• Tie bars – Keep your tie in place while showing that you care about the details. Wear tie bars for a finished look.
  
• Watches – From a smart watch to an ageless analog classic, watches add functional style to your look.
  
• Belts and dress socks – Assure an intentional, cohesive look – match your belt leather to your shoes and match your dress socks to your trousers.

How to Dress in Your 30s for Common Occasions

Building a strong wardrobe only works if you can pull the pieces together. This section illustrates how 30 somethings can assemble wardrobe essentials for five common occasions.

• The business casual office. Wear tailored chinos with an Oxford cotton button-down or a merino polo. Add an unstructured blazer if you need to notch up your look for important office events or meetings. Complete your look with suede lace-ups or Chelsea boots.
  
• The business formal office. Business professional office attire pairs a dark two or three-piece suit with a white or light blue dress shirt, a silk tie in a rep stripe or subtle pattern, a pocket square, and polished dark leather Derbies or Oxfords. 
  
• Weekend errands. The key to 30s weekend wear is to look pulled-together while staying comfortable. Long gone are the baggy hoodie and sweats of your 20s.
  
  • A clean neutral crew neck, tailored poplin shorts, and leather sandals or textile loafers will work well for warm weather. 
    
  • In cooler months, go for a quarter zip merino wool pullover with straight-fit dark wash jeans and textile or suede loafers.
    
  • Keep in mind that fit is as important with casual wear as it is at the office.
    
• Date night. Layer a blazer, leather bomber jacket, or merino sweater over an Oxford or denim button-down paired with tailored straight-leg pants and suede loafers. Date night outfits let you play with color and texture more than with office attire.
  
• Formal events such as weddings, galas, opening nights. The event dress code will dictate your attire.
  
  • Unless the event is black tie, you'll wear a dark suit paired with a crisp white French cuff dress shirt, a silk tie, a pocket square, minimalist cufflinks, and dark dress shoes. Inventive tie and pocket square pairings will keep your look young and 30s appropriate.
  • If the formal event is black tie, wear a midnight blue or black tuxedo, a white tuxedo shirt, a black silk bow tie, cufflinks, a white linen pocket square, and black patent dress shoes. Wearing a tuxedo to formal events is inappropriate unless the dress code specifies black tie.

How to Dress in Your 30s FAQs

What is the 3-3-3 rule for men's clothing?

The 3-3-3 rule states that you can achieve 27 various outfits by mixing three bottoms, three tops, and three pairs of shoes. The 3-3-3 rule is especially beneficial when packing for trips but it's also super helpful when deciding what to wear every morning. Instead of an overstuffed closet, your wardrobe stays clutter-free and you can focus on buying high quality basics that make you feel confident. 

Several tips help ensure this minimalist rule works: Make sure top, bottoms, and shoes are compatible. Plus, each item should contain both formal and casual elements (like fine fabrics and impeccable tailoring). 

The items in each category should be varied in order to maximize mixing. For instance, the shirt category should have items like a premium T-shirt, fine-knit polo or sweater, and a dress shirt. For bottoms, select tailored chinos, dark trousers, and dark-wash jeans. For shoes, go with minimalist leather sneakers, suede loafers, and dark dress shoes.

How should dressing change in your late 30s vs early 30s?

When asking how to dress in your late 30s, a man should still express his vibrant youthfulness – and by all means avoid grandpa styling. As you're transitioning from your early to late 30s, it's common to ask, "How should a 37 year old male dress?" 

In your late 30s, your attire will take on a more refined look. You'll focus on impeccable fit; high quality, durable fabrics; and balancing color choices so outfits look interesting and sophisticated. You can avoid the middle-age look by wearing stylish and fashionable accessories in creative designs and colors. 
 
In your late 30s, investment pieces such as a bespoke suit, a quality overcoat, and a high caliber watch start paying off. You've mastered the art of mixing pieces to maximize your wardrobe. Your taste for dressing well developed in your early 30s, and now, in your late 30s, you know that well-chosen pieces look and feel good, offer versatility, and enhance your confidence.

What is the 70/30 rule in men's fashion?

The 70/30 rule for men's fashion specifies how to build and balance a wardrobe. 70% should consist of base pieces, the neutral, timeless, classic essentials. 30% should be accent pieces, interesting, stylish, or statement pieces.

The base items include the neutral, quality staples that never go out of style. Well-fitted suits and blazers, neutral tailored trousers, dark-wash jeans, and well-maintained leather footwear. Timeless style and high-quality fabrics should be the hallmark of your base items.

The accent pieces should express your personal style. 30% of your wardrobe should include items that show your taste and individuality. This could be a vintage watch, a statement leather bomber jacket, a colorful floral silk tie, head-turning sunglasses, or a cool pair of retro sneakers.

When a man masters the 70/30 rule — shopping for clothing, getting dressed for work, building an array of handsome outfits, and keeping an organized closet — becomes far easier. Also, following this rule makes you confident that any outfit you put together looks polished and balanced.
