Suit Lapel Styles Explained: Notch, Peak, and Shawl, Which Is Right for You

The lapel is the folded flap of fabric that runs from the collar to the first button of a jacket. Most men have worn suits without thinking much about it. The choice of lapel style, however, communicates something specific about formality, intentionality, and context. Here is what each style means and how to choose.

The Notch Lapel

The notch lapel is the most common lapel style on business suits. It is identified by the triangular notch at the point where the lapel meets the collar. The V-shaped cut creates a clean, contained look.

Notch lapels read as professional, versatile, and conventional. They are appropriate for any business context. They are the safe choice and the right choice for most first and second suits.

Width matters with a notch lapel. A narrow lapel (under 2.5 inches) reads as fashion-forward and dates quickly as lapel width trends shift. A very wide lapel (over 3.5 inches) reads as either retro or very formal, depending on the width of the tie. The most durable choice is a medium lapel width in the 2.75 to 3.25 inch range, which corresponds roughly to the width of a standard necktie and sits well in proportion to most body types.

For most professional men in the Fraser Valley, a notch lapel in a medium width is the right choice for a first suit. It works across every professional context, ages without dating, and photographs correctly.

The Peak Lapel

The peak lapel is identified by the points that extend upward from the lapel toward the shoulders, past the collar seam. It creates a sharper, more formal silhouette than the notch.

Peak lapels are associated with double-breasted suits, tuxedos, and high-formality single-breasted suits. On a single-breasted jacket, a peak lapel adds intentional formality and is a clear style statement.

In professional contexts: peak lapels are appropriate for any business setting but carry a higher formality register. They read as decisive and deliberate. In creative or casual business environments, they may read as overdressed. In formal professional environments (law, finance, executive settings), they are entirely appropriate and often read as more polished than a notch.

For a man building a wardrobe, a peak lapel is typically the right choice for a second or third suit, once the versatile notch-lapel first suit is established. The peak adds a configuration that serves higher-formality occasions.

The Shawl Lapel

The shawl lapel is a continuous curved collar that runs from the back of the neck to the first button without the notch or peak cut. It is almost exclusively used on tuxedos and smoking jackets.

In a formal black-tie setting, a shawl lapel on a tuxedo is traditional and appropriate. On a business suit, it is almost never seen and would be conspicuous.

If you are ordering a tuxedo (Cardero offers a tuxedo conversion on any Super 120 or above suit for a $75 add-on), the shawl lapel is an option alongside the peak lapel. Shawl is more traditional and classic. Peak is sharper and slightly more modern in black-tie contexts. Both are correct. A vest with a shawl or peak lapel jacket is a particularly formal combination, the suit vest guide covers when adding a vest to the jacket makes sense at the wedding or formal event level.

Lapel Width and Body Proportions

Lapel width should be proportional to the body. A broader man in a very narrow lapel creates an imbalance. A slimmer man in a very wide lapel has the same problem.

The practical guide: the tip of the lapel should align roughly with the shoulder seam. The width of the lapel should roughly match the width of the tie knot at its widest point.

At a Cardero appointment, the lapel decision is made in the context of your shoulder width, chest width, and face shape. It is one of the design decisions that has meaningful impact on the final proportions of the garment. For men with broad shoulders, this proportional consideration is especially important, suits for broad shoulders explains how body width interacts with jacket design decisions including lapel width.

Which Lapel Style for Which Suit

First suit: notch lapel, medium width. Maximum versatility.

Second suit or formal event suit: peak lapel, single-breasted. Adds formality and visual authority.

Tuxedo conversion: shawl or peak lapel depending on preference. Both traditional for black-tie.
