Types of Suits for Men
The main types of men's suits are the single breasted suit (one row of buttons, the most common and versatile), the double breasted suit (two rows of buttons and an overlapping front for a dressier look), and the three-piece suit (jacket, pants, and a vest for extra formality). Beyond these, suits vary by fit (slim, modern, classic), lapel style (notch, peak, shawl), fabric, and color.

The Main Types of Men's Suits
These are the classic suit styles every man should know. They never go out of date and cover nearly every occasion.
Single Breasted Suit
A single breasted suit has one row of buttons down the front and a clean, straight closure with no overlap. It usually comes with one, two, or three buttons, and the two-button suit is the most popular choice. This is the standard suit most men picture, and for good reason: it works at the office, at weddings, at interviews, and at casual events.
The single breasted style is the most flexible suit you can own. You can dress it up with a tie or wear the jacket on its own with chinos. If you want one suit that does everything, start here. Browse the full men's suits range to see the options.
Best for: everyday wear, work, interviews, and most events.
Double Breasted Suit
A double breasted suit has two parallel rows of buttons and front panels that overlap across the body. Most use a six-button layout, and they almost always come with peak lapels for a sharp, structured look. The extra fabric and second row of buttons make this style dressier and bolder than a single breasted suit.
A double breasted suit gives off a confident, classic vibe that stands out at weddings and formal events. Modern cuts have made it easy to wear, so it no longer looks boxy like older versions. A slim fit double breasted suit keeps that strong look while staying comfortable and current.
Best for: weddings, evening events, business, and making an impression.
Three-Piece Suit
A three-piece suit adds a vest (waistcoat) to the jacket and pants. The vest adds formality and lets you take the jacket off without losing the dressed-up look, which is handy at long events like weddings. It works with both single and double breasted jackets, though it pairs most naturally with single breasted.
Explore the three-piece suit collection, or add a separate men's vest to a suit you already own.
Best for: weddings, formal events, and a polished, traditional look.
Single vs Double breasted
A single breasted suit is the easy, everyday choice, while a double breasted suit is the dressier, standout choice. Read our full guide on the difference between single and double breasted suits for more.
Quick Comparison: Suit Types at a Glance
| Suit Type | Buttons | Formality | Best For |
|---|---|---|---|
| Single breasted suit | One row | Versatile | Office, interviews, weddings, casual |
| Double breasted suit | Two rows, overlapping | Dressier, bold | Weddings, evening events, business |
| Three-piece suit | Jacket + pants + vest | More formal | Weddings, formal events |
| Tuxedo | Satin details | Most formal | Black tie, galas |
For black tie events, a tuxedo is the most formal option of all, with satin lapels and trim that set it apart from a regular suit.
Trending Suit Styles for Men
Classic suits are always safe, but a few modern styles are popular right now if you want to stand out.
- Patterned suits: Bold patterns like pinstripe, plaid, windowpane, and houndstooth add personality while still looking sharp. Great for less formal settings.
- Textured suits: Fabrics like tweed, linen, and velvet add depth and character. A tweed blazer brings a rich fall and winter feel, while a velvet tuxedo reads luxe for evening events.
- Bright and light colors: Moving past black, navy, and gray, lighter shades work well at summer weddings and outdoor events. A seersucker suit or linen suit keeps you cool and stylish in warm weather.
Mixing a classic cut with a fun pattern or color is a safe way to look fashion-forward without overdoing it.
Suit Fit Types for Men
Fit matters as much as style. The same suit can look great or sloppy depending on how it sits on your body. Here are the main men's fits.
Slim Fit
A slim fit suit is cut close to the body with a tapered waist and narrower legs. It gives a sharp, modern look and works well on leaner builds. It still allows enough room to move, so it is comfortable as well as stylish.
Modern Fit
A modern fit suit sits between slim and classic. It is tailored but not tight, with a little more room through the chest, waist, and legs. This is a safe pick for most men because it flatters straighter and more athletic builds without feeling baggy.
Classic Fit
A classic fit suit offers the most room through the shoulders, chest, and seat. It is comfortable and timeless, and it is a great choice if you want easy movement or a more relaxed look. Bigger and taller guys get clean, well-proportioned options in a dedicated big and tall suit range.

Suit Lapel Types
The lapel is the folded part of the collar, and it changes how formal a suit looks. There are three main types.
- Notch lapel: The most common and versatile, with a small V-cut where the collar meets the lapel. Usually found on single breasted suits and right for almost any occasion.
- Peak lapel: More formal, with edges that point up toward the shoulders. Common on double breasted suits and formal jackets for a sharp, structured look. See bolder options in wide lapel suits.
- Shawl lapel: Smooth and rounded with no notch, usually reserved for tuxedos and evening wear for an elegant finish.
Suit Fabrics and Seasons
The fabric decides how a suit feels and when you can wear it.
- Wool: The all-rounder. A mid-weight wool suit holds its shape and works most of the year, which suits structured styles like a double breasted suit.
- Linen and cotton: Light and breathable for hot weather. A linen suit is perfect for summer weddings and outdoor events.
- Tweed and heavier weaves: Warm and textured for fall and winter, great in richer colors and patterns.
- Velvet: Soft and luxe, best for evening and holiday events.
Simple rule: heavier, structured fabrics flatter dressier suits, while lighter fabrics keep everyday suits comfortable.
How to Personalize Your Suit
Once you have the style and fit down, the details make the suit yours.
Accessories
Small pieces make a big difference. A tie, pocket square, watch, or a quality dress shirt can change the whole feel of an outfit. Pick bold or classic depending on the occasion.
Mix and Match Separates
You do not always need matching pieces. A patterned jacket with solid slacks, or a tweed vest with a different jacket, can create a unique look. A standalone blazer or sport coat gives you even more mixing options.
Shoes
The right shoes finish the look. Black or brown dress shoes are the classic choice, but you can experiment with other colors or dress sneakers if the event allows.
How to Choose a Suit for Any Event
Match the suit to the occasion and you will always look right.
- Business meetings: A single breasted, modern fit suit in navy or charcoal is clean and professional without being flashy.
- Weddings: Follow the dress code, then add personal style. A three-piece suit, a double breasted suit, or a wedding suit all make a statement. For summer or outdoor weddings, go lighter in color and fabric.
- Formal and black tie: Reach for a tuxedo with satin details and a shawl or peak lapel.
- Casual events: A patterned or light-colored suit, or suit separates worn with jeans or a button-down, hits the right relaxed note.
