It’s true that three piece suits are formal attire, but not for every occasion. In order to align with modern style etiquitte, you should wear a 3 piece suit primarily at social or celebratory occasions like weddings, anniversaries, dinner parties, performances, and even funerals.

Simply put, a three-piece suit is composed of the usual components of a two piece suit, a jacket and trousers, with the addition of a layered third piece: a vest or waistcoat. Any suit or tuxedo that combines these three elements would fit under the definition of three piece suit. Three piece suits are the epitome of class and are a great way to bring your style up a notch — but only when it’s deemed appropriate. 

Three-piece suits are broken down into three components:

Three-Piece Suit vs Two-Piece Suit: The Main Differences

Really, the difference between a three-piece suit and a two-piece suit is quite simple—a three-piece suit includes a vest (worn over your shirt and under your suit jacket), while a two-piece suit doesn’t. Many two piece suits will come with the option to include a vest (like ours), this gives your suit the ability to transition between a two pieces look and three depending on the occasion.

There are also differences between where you can wear the two variations that are slightly more involved. 

When To Wear A Three Piece Suit 

As mentioned earlier, when considering when to wear a three piece suit, it’s critical to understand the modern standards that determine its appropriateness for certain situations. It’s the perfect suit for a formal occasion, such as a wedding or a luxe anniversary dinner, but less so when worn to work or when conducting business.

The addition of a vest or waistcoat in current style etiquitte is often considered playful, or a novelty—meaning it has little place in modern business attire. However, that same playfulness is perfect for helping pull a wedding theme or venue into your outfit, or add a bit of flair when dining on a special occasion.

How To Style A Three Piece Suit

If you want to amp up the traditional style of dressing for a formal event, the three-piece suit can be just the piece to do that. However, many people wonder: is a three piece suit too formal? While they are a sophisticated look, you have to be selective on when to wear a three piece suit.

Here are a few things to consider if you want to know how to wear a three-piece suit: 

#1: Focus on Fit.

When it comes to a vested suit (or any suit, for that matter), fit is the most important element for it to really shine – there’s nothing worse than a poorly fitted suit. When you can, opt for a custom-made suit to be sure you’ll get the perfect fit.

#2: Choose High-Quality Fabrics.

This suit should be worn for special occasions, which calls for formal-appropriate high-quality fabrics. If you wear a three-piece suit made with cheap materials, you’ll end up looking cheap! Choose a suit with a quality fabric like tweed or linen. 

#3: Match Your Colors.

The vest, dress pants, and suit jacket should almost always match in both color and pattern. If the event is less formal, like attending a wedding (that isn’t black tie), you might add a contrasting vest. You can occasionally even contrast your trousers, but reserve this for formal dinners. However, contrasts vest can go wrong quickly, and are often not considered stylish in today’s day and age—so choose wisely.

Remember, lighter is more casual, and darker is more formal. You can also try a different shade of pant or bow tie, just as long as everything still coordinates at the end. 

#4: Choose the right accessories.

When considering when to wear a three piece suit, you should also consider the accessories to accompany it. At the very least, wearing a tie or bowtie is a must. We’d also highly recommend the addition of a pocket square that complements the tie (but doesn’t match it, that’s tacky!). This will help break up the large blocks of color/pattern of the jacket, vest, and trousers.

These pops of color should always be an important consideration in when to wear a three piece suit to ensure your outfit looks balanced and intentional.
