What Is A Suit Jacket For?

A suit jacket is a key part of a 3-piece suit ensemble. Usually worn over a formal shirt and waistcoat, they are that last touch of formality that completes the look. They are the most formal jacket out there, and they elevate any outfit as a result. They are also built to flatter the wearer, creating a silhouette that accentuates the shoulders and brings in the waist, creating a quintessential V shape.

 

 

However, exactly what a suit jacket does is up to the wearer and the suit itself. Different types of suit jacket will end up in different results in a look and on a specific wearer. There are different ways to get the perfect suit jacket, read on to find advice and tips to find the right men’s suit jacket for you…

How Should A Suit Jacket Fit?

Suit jacket fit is a key step in finding the best men’s suit jacket that cannot be ignored. A jacket that is too big will hang off your frame, making you look bulky. A jacket that is too small will pinch, be uncomfortable, and make you look bigger than you are. The perfect fit is somewhere between these two and will create a smooth silhouette, making for a lasting, formal impression.

 

 

Here are some aspects to look for in finding the right suit fit.

 

 

The shoulder should lie flat. The shoulder seam should hit on top of where your arm and shoulder connect. There should be no excess material, but it also shouldn’t ride up and have the arms start over your shoulder. This aspect is extra important as this is not an easy fix in tailoring, the suit jacket must fit here from the beginning to ensure the best overall fit.

 

 

The jacket needs to be able to close. When it is closed, the two sides should neatly meet without hanging off the body or the material pinching inward and flaring out at the bottom. There should be no strain in shutting the button and no wrinkling of the material. It should hug the body but not constrict. Ultimately, it should be comfortable.

The jacket sleeve should expose just a slither of the cuff of a formal shirt worn beneath it. The traditional guideline is ‘half an inch of linen’, meaning only half an inch of the shirt should show. The cuff of the shirt, and just above it, should never show entirely. The shirt should also never be completely hidden. For most men, the jacket should stop just before the large wrist bone. Sleeve jackets are one of the easier tailoring adjustments, but you should still aim to be in the ballpark – tailors can’t make miracles after all!

 

 

Your jacket collar should rest against the collar of your formal shirt, which should hug your neck also. There should be gaps between all of these, but not big ones. Often, a badly fitting collar is symptomatic of other aspects of bad fit in a jacket, particularly shoulder fit. If a collar is too tight or too loose, it may be worth trying on different sizes and styles all together.

 

 

Lastly, jacket length is important to getting the right overall look from a suit. It should fall past the waist and past the top of the trouser. It should drape over the top of the buttock but stop just about where the buttock begins to curve inward. It should ideally hit the middle of the hands, when they are relaxed to the side of your body. If the jacket stops before the buttock or goes past the hands entirely, the jacket length is not right.

 

 

A good starting point to getting the right fit and figuring out the right suit sizes for you is utilising a size guide. Take your measurements, apply them to the size guide associated with your desired suit, and then try that size and the size larger and smaller. With these steps, you should streamline finding the right size and be able to take the above information into finding the best men’s suit jacket size for you.

Single-Breasted Suit Jackets vs Double-Breasted Suit Jackets

One major difference in some jackets is that some will be single-breasted, and others will be double-breasted; this is also applies to waistcoats. A single-breasted suit jacket will have one line of buttons down the centre of the suit. A double-breasted suit jacket will have two lines of buttons with a cross over of material. Both styles have their pros and will work better for certain styles and individuals.

 

 

Of the two, the double-breasted suit jacket is the older and more traditional style. The cross over of the fabric creates a more structed body to the suit jacket, making for a strong silhouette. However, to effectively work, it needs to be well-fitting. It also generally can be more flattering for medium or larger built men, as there is more for the suit to structure. It brings attention to the upper chest and attention to the intricate details of the lapels, a common feature of the double-breasted jacket.

 

 

A single-breasted jacket is a more contemporary style. The simplicity of the V neck lapel into a straight line of buttons down the torso brings attention to the upper chest and makes for an easily flattering suit look. Often slimming, the streamlined suit look makes for a suit that you can accessorise and style as you please.

 

 

Ultimately, whether you should wear a double-breasted or single-breasted jacket is really up to your preference. Try on styles in each and see what makes you feel your best.
