A man wearing a tailored suit jacket, perfectly fitting his body type and posture, showcasing the importance of adjustments for off-the-rack suits.

Fact 2: Not All Men Are Built the Same (But You Can All Dress Fantastically)

Two men standing side by side, both wearing similar basic suits, but the fit is noticeably different. One man’s suit fits perfectly to his body, highlighting the sharp lines and smooth silhouette. The other man’s suit is slightly off, showing how ill-fitting suits look bulky and unflattering. Both men should exude confidence, but the well-fitted suit makes the first man stand out. Clean, minimalist background, soft lighting, high-resolution, focus on the fit, not the trends

The same suit can look very different on two people. Focus on fit first, not fashion trends. A well-fitted basic suit will always look better than a flashy, ill-fitting one.

Fact 3: Personal Style Is a Thing

A man confidently wearing a stylish suit with distinct personal touches. The suit features subtle patterns, a mix of classic and modern lapels, and unique pocket styles--perhaps a patch pocket or angled pockets.

The background should be clean and minimalist, focusing on the details of the suit, with soft lighting highlighting the textures and features. High-resolution, editorial style

Lapels for All Types of Suits

Notch Lapels

Formal suit jackets often with satin details. Paired with shawl or peak lapels. Strictly for black-tie events.

Talking Canvas

The canvas is the layer between the outer fabric and the inner lining of a suit jacket. It gives the jacket structure and helps it shape to your body over time. Jackets can be full canvas, half canvas, or fused. Here’s what each type means:

Full Canvas

A full canvas jacket has a layer of canvas that runs from the shoulders all the way down to the bottom of the jacket. This construction allows the jacket to drape naturally and conform to your body with wear. It’s breathable, durable, and high quality—commonly used in high-end or custom suits. If you’re looking for the best fit and feel (and don’t mind the cost), go full canvas.

Half Canvas

A half canvas jacket uses canvas material from the shoulders to the middle of the chest. Below that, the jacket is fused. It still offers a good structure and contouring, but at a lower cost than full canvas. For most men, this option gives the best balance between quality and price.

Suit Shoulders

Suit shoulders can change the look and feel of your entire jacket. The type of shoulder affects structure, silhouette, and how formal the suit appears.

Sloped

A man wearing an unstructured blazer with natural shoulders, following the natural shoulder line for a relaxed, less structured fit. The blazer looks effortless and casual, perfect for informal occasions. The relaxed silhouette flatters sloped shoulders, creating a comfortable, laid-back appearance.

Straight

A man wearing a formal suit with padded shoulders, creating a sharp horizontal line for a defined, strong look. The suit jacket has structured shoulders that emphasize a commanding presence, ideal for business and formal settings. The tailored fit enhances the bold and powerful silhouette. The lighting highlights the sharp lines and formal vibe of the suit, showcasing the sophisticated style. Editorial style, clean lines, high-resolution, cool tones

This style uses padding to create a sharp horizontal line across the shoulders. It adds definition and gives off a strong, commanding presence. Common in business and formal suits.

Roped

A raised bump or ridge where the sleeve meets the shoulder. Often used in Italian tailoring. It gives a more pronounced, elegant shoulder and works well in fashion-forward or high-end suits.

The Suit Vent (And Why It Matters)

Suit vents are the slits at the back of your jacket. They help you move more freely and also affect the way the suit drapes on your body. There are three main types of vents, and each one has its strengths.

Center Vent

A man wearing a classic American-style suit with a single slit in the middle of the back. The slit allows for modest movement and comfort while walking or sitting. The suit is tailored for a clean, professional look, ideal for business or day-to-day settings. The back of the jacket remains smooth and structured, with subtle details emphasizing the simplicity and functionality of the design. Editorial style, high-resolution, neutral tones

A single slit in the middle of the back. Common in American suits. It allows for modest movement, especially when walking or sitting. However, it can spread open and bunch up when you place your hands in your pockets. Good for a clean, basic look in business or day-to-day settings.

Side Vent

Also known as double vents, these are two slits on either side of the jacket’s back. They provide greater freedom of movement and help keep the jacket from creasing or bunching when seated. Side vents also create a smoother drape and often look better when you’re in motion. Favored in British tailoring and modern business styles.

No Vent

A man wearing a sleek, formal ventless suit jacket, with a solid back panel and no slits. The design offers a polished, refined silhouette, perfect for tuxedos or eveningwear. The jacket fits perfectly, creating a sharp, elegant look, though slightly restricting movement due to the ventless construction. High-resolution, editorial style, dark tones, formal setting

A ventless jacket has a solid back panel with no slits. This design offers a very sleek and formal silhouette. It’s typically found in tuxedos and eveningwear. It gives a polished look but restricts movement more than the other types.

Pockets

Pockets are one of the most overlooked but telling features of a suit jacket. They affect not just function, but formality, structure, and the overall feel of your look.

Patch Pockets

These are sewn directly onto the outside of the jacket. They’re casual, relaxed, and perfect for unstructured blazers and summer suits. They work well for date nights, travel, or any event that doesn’t call for strict formality.

Welt Pockets

A man in a formal tuxedo with hidden, minimal slits on the jacket. The design is sleek and elegant, maintaining a slim silhouette. The tuxedo is perfect for black-tie events, offering a clean and refined appearance. The look is polished and sophisticated, ideal for high-end formal occasions.

These are minimal slits, almost hidden, and typically found on tuxedos or very formal jackets. They offer a clean, elegant appearance and help maintain the jacket’s slim silhouette. Use these for black-tie events or formal business wear.

Jet Pockets

A step above welt pockets in visual detail. These have a narrow border around the opening, adding subtle structure. Jet pockets are often seen on higher-end suits and strike a nice balance between simple and refined.

Angled Pockets

A man in a modern European-style suit featuring slanted pockets that diagonally cut from the outside in. The slanted pockets elongate the torso and add flair to the classic suit, giving it a dynamic, stylish look. The suit is sharp and contemporary, perfect for a man who enjoys a bit of movement and modern style. High-resolution, clean lines, vibrant lighting

These slant diagonally from the outside in. They elongate the torso and add a little flair to otherwise classic suits. They’re often found on modern or European-style jackets and work well for men who want a bit of movement in their look.

Ticket Pockets

The pocket, originally designed for holding train tickets, adds a touch of classic, refined character to the jacket. The suit exudes an air of sophistication, with sharp tailoring and attention to detail. High-resolution, warm lighting, classic and elegant look

A small pocket placed just above the right main pocket. Originally used to hold train tickets, today it’s mostly decorative. It gives off a traditional, British tailoring vibe and adds some character to more formal jackets.

What Type of Suit You Should Choose by Occasion

Weddings

A wedding can be formal, casual, or themed, so read the invitation closely. For formal weddings, go with a darker suit (navy, charcoal) and peak or notch lapels. If it’s a black-tie event, wear a tuxedo with a shawl lapel. For outdoor or beach weddings, lighter fabrics like linen or cotton and light colors like beige, stone, or pastel blue work well. Pair with a modern fit and minimal pattern.

Job Interviews, Corporate Meetings, and the Office

Stick to business colors like navy, dark gray, or black. A classic or modern fit works best. Look for subtle patterns like pinstripes or checks if you want a bit of style without standing out too much. Stick with notch lapels and side vents for comfort and a polished look. Avoid patch pockets and bright colors. Pair with a clean dress shirt and conservative tie.

Date Nights

You want to look relaxed but put together. This is where an unstructured blazer or casual sport coat shines. Soft shoulders, no padding, maybe a patch pocket or two. Try textures like tweed or cotton blends. Pair with a simple button-up or even a clean T-shirt. You can wear it with jeans or chinos. This is the best type of suit jacket to wear with jeans without looking overdressed.

Cocktail Parties and Semi-Formal Events

Choose a modern-fit jacket in a bold color or with a subtle pattern. Shawl or peak lapels can add a little flair. Consider a double-breasted option if the event leans upscale. Jet or angled pockets and a side vent offer a clean silhouette while maintaining comfort.

Funerals and Memorial Services

Stick with a dark, classic suit: black, charcoal, or navy. A classic fit, notch lapel, and minimal design are best. Avoid patterns and loud accessories. It’s not about standing out—it’s about showing respect.

Travel and Business Trips

Look for wrinkle-resistant fabrics and minimal structure. A half-canvassed, modern-fit blazer with straight shoulders and a center or side vent offers flexibility and comfort. Stick with neutral colors to make mixing and matching easy.
