🧥 Choosing the Right Blazer

A well-chosen blazer can instantly upgrade any outfit—from casual Fridays to semi-formal events. When picking one, focus on fabric, fit, and color.

🎨 Fabric: Go for lightweight cotton or linen in summer, and wool or tweed for cooler months.
✂️ Fit: It should contour your shoulders and taper at the waist without feeling tight.
👔 Color: Navy, charcoal, or gray are the most versatile and work with almost any shirt or pants.

A good blazer strikes the balance between comfort and class, letting you look sharp without overdoing it.

Best Shirts to Wear Under a Blazer

The shirt you wear under your blazer sets the tone for your outfit. Some shirts look more formal, while others lean casual.
Here are the top shirt types that work best with blazers.

1. Classic Dress Shirts

A classic dress shirt is the safest and most versatile choice. It’s perfect for business, weddings, and formal dinners.

Key features:

• Stiff collar
  
• Long sleeves with button cuffs
  
• Usually made of cotton or a cotton blend
  

Best combinations:

• White dress shirt + navy blazer = clean and formal look
  
• Light blue dress shirt + gray blazer = sharp business look
  
• Pale pink or lavender shirt + dark blazer = modern and stylish
  

Tip: Make sure your dress shirt fits well. Avoid excess fabric around your waist or shoulders. A slim or tailored fit works best under a blazer.

2. Button-Down Shirts

A button-down shirt has small buttons on the collar tips. It’s slightly more casual than a dress shirt but still neat enough for work or semi-formal settings.

Best for: Smart-casual or business-casual occasions.

Best combinations:

• Light denim button-down + beige blazer = relaxed yet sharp look
• White button-down + navy blazer = safe choice for any occasion
• Patterned button-down (like stripes or checks) + solid blazer = adds texture and interest
  

3. Oxford Shirts

An Oxford shirt is made from thicker fabric with a slight texture. It’s more casual than a dress shirt but looks great under structured blazers.

Best for: Business-casual offices, dinners, or weekend events.

Best combinations:

• Light blue Oxford + gray or navy blazer = classic and easy to wear
• White Oxford + tan blazer = great for daytime or spring events
• Striped Oxford + dark blazer = stylish mix of texture and contrast
  

4. Round-Collar Shirts

Also known as club-collar shirts, these have rounded edges instead of pointed ones. They give a vintage or dressy look.

Best for: Stylish or semi-formal settings.

Best combinations:

• White round-collar shirt + charcoal blazer = old-school charm
• Pale blue round-collar shirt + navy blazer = perfect for dinner events

5. Polo Shirts

A polo shirt works surprisingly well under casual blazers. It’s ideal for warm days when you want to look smart without feeling overdressed.

Best for: Casual Fridays, lunches, or weekend outings.

Best combinations:

• White or navy polo + light gray blazer = clean summer look
• Black polo + tan blazer = modern contrast
• Striped polo + solid blazer = sporty yet neat
  

How to Make Sure Your Blazer and Shirt Fit Properly

Fit matters more than anything else. Even the best shirt looks bad if it’s too tight or too loose.
Here’s how to check that both your blazer and shirt fit correctly.

📏 Blazer Length

The bottom of the blazer should cover your seat for a balanced and clean look. When your arms hang naturally, the blazer should end around your knuckles. A blazer that’s too short may look trendy but often doesn’t fit well in formal settings.

💪 Shoulder Fit

The blazer’s shoulder seam should sit right at the edge of your shoulder for a sharp and natural look. Wrinkles near the shoulder mean the blazer is too tight, while sagging shoulders mean it’s too big.

✋ Sleeve Length

The blazer sleeve should stop around your wrist bone, with about half an inch of your shirt cuff showing beneath it. This subtle detail gives your outfit a clean, balanced, and well-fitted look.

👔 Shirt Fit

The shirt collar should sit close to your neck without choking you, while the shoulder seams should align perfectly with your shoulders. The shirt should also stay tucked in when you move, keeping your outfit neat and comfortable all day.

Matching Your Blazer and Shirt to the Occasion

Different occasions call for different levels of formality. The right combination of blazer and shirt ensures you look appropriate and well-dressed wherever you go.

🎩 Formal Events
Opt for a dark blazer in navy, charcoal, or black. Pair it with a crisp white or pale blue dress shirt for a sharp, classic look. Complete the outfit with a tie, pocket square, and polished leather shoes.

💼 Business Casual
Choose a navy, gray, or brown blazer with an Oxford or button-down shirt. You can skip the tie if the setting allows, and finish with loafers or brogues for a neat, professional appearance.

🧢 Casual Settings
For a relaxed look, go with an unstructured or linen blazer in lighter shades. A polo or casual button-down shirt works well underneath. Keep it simple with no tie and wear clean sneakers or loafers.

🌙 Evening or Date Night
Pick a blazer in deeper tones like black, dark green, or burgundy. Pair it with a black or subtly patterned shirt for a modern, confident style. Add a sleek watch and slim leather belt to complete the look.
