Suit vests, while not as ubiquitous as they once were, still exude timeless style in men’s fashion. In this post, we’ll delve into the nuances of suit vests, including the rules governing their wear alongside suits. From formal black-tie occasions to the more modern blue tuxedo ensembles, we’ll explore the breadth of men’s sartorial elegance. While the regulations surrounding suit vests may not be extensive, they’re nonetheless essential to grasp. Today, we’ll navigate through these guidelines and provide you with a comprehensive understanding of suit vests. So, without further ado, let’s dive in and explore: What are the rules for wearing a suit vest?

Is there a distinction between a suit vest and a waistcoat?

The primary distinction between a suit vest and a waistcoat lies in the terminology. In the United States, the garment is commonly referred to as a suit vest, while in the United Kingdom, it’s known as a waistcoat. Despite the naming difference, both are sleeveless garments designed to be worn atop a shirt.

However, some argue that a waistcoat carries a higher level of formality compared to a vest. Traditionally, a waistcoat is an integral part of a three-piece suit ensemble, typically worn with a jacket and trousers, while a suit vest is often worn independently over a button-down shirt.

Mastering the rules regarding vest and suit buttons is key to confidently and stylishly wearing your suit vest, whether you’re donning it for a day at the office or a friend’s wedding.

Buttoning Your Vest

While we’re not staunch followers of rigid rules, there’s one we firmly advocate: never button the last button. Whether you’re wearing a vest or not, fastening the bottom button can give off an unsophisticated vibe.

If you’re sporting a vest, leave the bottom button undone. For tips on wearing a vest casually on its own, check out our guide here.

Suit Buttoning Rules With a Vest

When it comes to the tradition of buttoning your suit while standing and unbuttoning when seated, there’s a bit of flexibility to consider.

When you’re seated, it’s definitely advisable to unbutton your suit. Keeping it fastened while seated can strain the button closure, potentially leading to wardrobe malfunctions. Adding a vest to the mix only adds more pressure on the button, resulting in an awkward pulling sensation across the chest and back.

However, when you’re standing, adhering to formal etiquette dictates buttoning up. Conversely, sporting a three-piece suit with the vest buttoned and the jacket open can emit a relaxed, confident vibe that’s undeniably stylish.

Ensuring the Proper Fit of a Suit Vest

Understanding the proper fit of a suit is crucial knowledge for every man. This is particularly important when it comes to your suit vest. A properly fitted vest elevates the entire ensemble, while an ill-fitting one detracts from it. For this reason, investing in a suit vest tailored to your measurements is highly recommended.

Here are some key considerations to keep in mind:

The Body

A suit vest should hug your body closely, offering a slim fit that enhances your silhouette without feeling restrictive. It’s important that it’s not overly tight, as this can give the impression of straining against the fabric. A slight taper at the waist enhances the vest’s aesthetic appeal.

Additionally, an adjustable buckle at the back of the vest is ideal. This feature allows you to customize the fit, ensuring comfort and versatility as you can tighten or loosen the vest as needed.

The Length

Achieving the proper length for your suit vest is essential for a well-fitted appearance. Fortunately, determining if the length is right is relatively straightforward. In essence, the vest should extend just over your waistband, ensuring that no portion of your shirt is visible underneath it.

Selecting the Perfect Suit Vest

When investing in a suit vest, longevity is key. Therefore, prioritize versatility and a proper fit when making your selection. Here are six essential tips to consider when purchasing a men’s vest:

#1: Opt for Consistent Material

Choose a waistcoat crafted from the same fabric as your suit to maintain a cohesive and polished look. Mismatched fabrics can result in an awkward and disjointed ensemble. Therefore, opt for a wool vest if your trousers and jacket are wool, or select a linen vest if the rest of your suit is linen, and so on.

#2: Embrace the V-Neck Opening

The neck hole or opening plays a crucial role in how the vest material drapes and conforms to your body. It’s essential that it snugly hugs your body, particularly around the back of your shirt collar, without bunching up or leaving gaps. Opting for a v-neck opening not only accentuates your suit but also allows your dress shirt collar to be more prominently displayed.

#3: Coordinate Colors

The vest typically complements the color and fabric of the jacket and trousers. For instance, opt for a darker vest shade if your suit is black or any other dark hue. If your suit jacket features patterns, ensure that the vest matches these patterns. In the case of a black-tie affair, your three-piece suit ensemble, including the vest, should be entirely black.

However, you can also choose a vest color that contrasts with your suit, as long as it adheres to the color wheel. For instance, a light gray vest pairs nicely with a royal blue suit ensemble.

#4: Mind the Length

As previously highlighted, the length of the vest is paramount. It should ideally extend to cover your waist and hang approximately an inch below the waistline of your pants. Your shirt should never be visible beneath the vest; if it is, this indicates that the vest is too small.

#5: Opt for Quality Buttons

Your waistcoat typically features an odd number of buttons, although this might vary based on your height. A standard 5-button vest might not complement men taller than 6 feet; in such instances, a 7-button waistcoat is more fitting.

Button quality is essential. Opt for waistcoat buttons crafted from embossed metals like silver, brass, or mother of pearl for durability and elegance. Ideally, they should be fashioned from natural materials, as buttons made from cheaper alternatives are prone to breakage and quicker deterioration.

#6: Examine the Pocket

Quality vests typically feature a functional pocket. These are often sewn shut with tack stitching to maintain the vest’s shape. Upon purchase, simply snip the threads to open up the pocket. Additionally, refrain from storing bulky items in your suit pockets, as this can impact the shape of your vest.

Common Inquiries

There’s a plethora of nuances surrounding suits and suit vests, leaving many guys with numerous questions. Here are some of the most frequently asked questions about suit vests:

What’s the best way to clean a suit vest?

To ensure the longevity of your suit vest, proper cleaning is essential. We recommend dry cleaning your suit vest for optimal results.

To prevent wrinkles, be sure to hang your suit vest properly. If wrinkles do occur, use a suit steamer set on low heat to gently remove them. Avoid ironing your suit vest, particularly if you’re uncertain about the appropriate temperature setting.

Is it necessary for the vest to match the pants?

Is it advisable to coordinate your vest with your jacket and trousers? The answer is both yes and no. While it’s not always necessary for them to match, the ensemble exudes a particularly stylish flair when they do. If you’re considering purchasing just one suit vest, it’s recommended to opt for a matching set with your suit. This ensures you always have the option of a three-piece suit ensemble. On the other hand, not matching the vest to the trousers creates a noticeably more casual aesthetic. If you’re intrigued by this approach, we’ve dedicated an entire guide to wearing a suit vest casually.

Is it acceptable to wear a vest without a jacket?

Absolutely. Wearing a vest without a jacket can create a stylish ensemble. However, I recommend steering clear of vests made of shiny materials. When opting for a vest sans jacket, it’s even more crucial that it fits impeccably (refer to the guide above for fitting tips).

Is it acceptable to wear a three-piece suit without the vest?

Certainly. A three-piece suit, featuring the vest, represents a more formal attire option compared to a standard two-piece suit ensemble. However, if you choose to omit the vest, it no longer qualifies as a “three-piece suit.”


Sporting a suit vest is an excellent means to exude sophistication and charm. Whether donning it casually or as part of a three-piece suit ensemble, you’re sure to make a stylish statement. Just remember to invest in a high-quality vest that is tailored to fit your body impeccably.
