Today, dress codes have become more relaxed, especially in the wake of remote and hybrid work. However, certain situations—such as important client meetings or job interviews—still call for a well-tailored business suit. Whether you’re stepping into a high-stakes meeting or making a strong first impression at a job interview, choosing the right suit is key.
At McCann Bespoke, we believe a business suit is more than just clothing; it’s a statement of professionalism, confidence, and leadership. To help you make the right choice, we’ve put together a guide covering everything from suit styles and fabrics to lapels and accessories.
What is a Business Suit?
A business suit is traditionally a two-piece ensemble—though a three-piece option with a waistcoat is also acceptable—designed for formal workplace settings. It usually includes a single- or double-breasted jacket paired with flat-fronted or pleated trousers. Common colors for business suits include navy, charcoal, and grey, while subtle patterns like checks can also work for a refined yet stylish look.
Even in a modern corporate environment with evolving dress codes, a well-fitted business suit remains an essential wardrobe staple for professionals looking to make an impact.
Single-Breasted vs. Double-Breasted Suits
The majority of business suits are single-breasted, featuring two or three buttons. This classic style has remained virtually unchanged for decades and is the go-to choice for a refined, professional appearance.
For those who want to make a stronger statement, double-breasted suits (DB suits) offer a bolder look. Once synonymous with 1980s “power dressing,” double-breasted suits have made a modern comeback, often with more tailored, relaxed fits. While DB suits provide a more structured silhouette, they require careful styling to ensure a sharp and polished finish.
Business Suit Styling Tips
When selecting a business suit, your priority should be professionalism and fit rather than simply making a fashion statement. That said, you can still inject personality into your look while maintaining a smart appearance.
- Invest in Multiple Suits: Once you find a cut that suits your frame, consider purchasing it in three or four different colors and fabrics. This allows you to mix and match with various shirts and ties for endless outfit combinations.
- The Right Fit is Key: A well-tailored suit should enhance your posture and frame without feeling restrictive.
- Keep Accessories Minimal: Opt for understated cufflinks, classic leather belts, and a sophisticated work bag to complement your look without overwhelming it.
Business Suit Etiquette: Do’s & Don’tsJacket Buttoning Rules
- Single-breasted suits (three buttons): Follow the “sometimes, always, never” rule—button the top one occasionally, always fasten the middle button, and never button the bottom one.
- Double-breasted suits: Traditionally, all buttons with buttonholes should be fastened, but it is acceptable to leave the bottom button undone.
Best Business Suit Colors
- Navy & Charcoal: The most versatile and professional options.
- Mid-blue & Light Grey: Suitable for less formal business settings.
- Black: Avoid unless attending funerals or working in hospitality/service industries.
Plain vs. Checked Fabrics
- Plain suits are a safe, traditional choice.
- Checked suits (e.g., Prince of Wales check) add subtle texture and visual interest while remaining business-appropriate.
- Sharkskin fabric—a textured, two-tone fabric—offers a modern, polished look.
Choosing the Right Suit Fabric
The best business suits are crafted from worsted wool, known for its durability and year-round versatility. Depending on the season and frequency of wear, consider the Super number (which indicates fabric fineness):
- Super 110-130: Ideal for daily wear, offering durability without compromising elegance.
- Super 140-160: More refined and luxurious—best reserved for important meetings and special occasions.
Keep in mind that higher Super numbers result in softer, more delicate fabrics that require extra care.
Suit Lapels: Notch vs. Peak
The type of lapel on your business suit influences its formality:
- Notch Lapel: The most common and versatile option, ideal for single-breasted business suits.
- Peak Lapel: Found on double-breasted jackets, offering a more structured and authoritative appearance.
How Should a Business Suit Fit?
An impeccable fit is non-negotiable when it comes to business suits. Here’s what to look for:
- Shoulders: The seam should align with your natural shoulder line.
- Chest & Waist: A close fit without pulling when buttoned.
- Sleeves: Should end at your wrist, allowing about half an inch of shirt cuff to show.
- Trousers: Aim for a slight break (the crease should just touch your shoe) for a polished finish.
For the best results, consider professional tailoring to achieve a custom-fit suit that complements your physique.
The Perfect Business Shirt
To complete your business look, pair your suit with a crisp, high-quality cotton-poplin or twill shirt.
- Best Colors: White, pale blue, or pastel shades like lilac and mint.
- Patterns: Subtle checks (windowpane, gingham) work well with plain suits, but avoid loud prints.
- Collar Styles: Point, spread, or cutaway collars provide a refined look.
For a more formal touch, double cuffs with cufflinks elevate your style.
Selecting the Right Tie
While ties are optional in some workplaces, they remain essential for formal business attire. Stick to classic silk or satin ties in subtle patterns:
- Solid Colors: Navy, burgundy, or muted tones.
- Patterns: Stripes or micro-dots add personality without being overpowering.
- Avoid: Loud prints, novelty ties, or overly bright colors.
Smart Business Shoes
A high-quality pair of leather dress shoes completes any business outfit. The best options include:
- Oxfords: The most formal and polished choice.
- Derby Shoes: Slightly more relaxed but still business-appropriate.
- Monk Straps: A stylish alternative for those wanting to stand out.
- Brogues: Acceptable but best suited for less formal business environments.
Stick to black or dark brown for versatility, and ensure your shoes are well-polished for a sharp appearance.
Essential Business Accessories
Less is more when it comes to accessories. Keep it professional with:
- Leather Belts: Match the color of your shoes.
- Work Bags: A leather briefcase, folio, or messenger bag ensures a polished look.
- Cufflinks & Watches: Keep metals consistent (gold with gold, silver with silver).
- Scarves: In colder months, opt for a cashmere or wool scarf in a neutral or subtle striped design.
