One great reason, which has many different expressions, for wearing a three-piece suit, is to make a statement. A three-piece tends to have it over a simple two-piece when you are aiming to achieve this. Wearing a three-piece might be a way to acknowledge the importance of a customer at a business interview; or to show the serious nature of a public speech or presentation. It might be to emphasize the high stakes when making a charity appeal, or if holding an auction for good causes, at a formal dinner.
When you are part of such occasions, it can also pay to tone down your choice of shirt color, and perhaps your tie as well. Let the quality of the suit stand out in its statement-making role.
It’s also a way to make an impression. If you are representing a major financial institution to current or potential investors, it’s a means of adding heft to the impression of your organization. On the personal side, it can be a terrific way to remind your partner of their importance to you, say on a date night. When attending a wedding, perhaps even as the groom, or an anniversary celebration, a stylish three-piece suite says that you know the importance of such an occasion.
Thirdly, a three-piece suit can also be an expression of how you see yourself. It is a feel-good investment, great for those times when you want to big yourself up and add some confidence.
Much More To A Three-piece Suit Than The Whole!

There are many further reasons for investing in the style and quality that a three-piece suit can bring to the occasions mentioned above, and many others. Many people see it as a single item, and yet it can also give you flexibility.
There can be occasions when you might discard the jacket; for instance, a waistcoat-clad presenter can suggest energy, with the jacket discarded early on as a statement of this. Furthermore, the best impression is often made by leaving the bottom waistcoat button open. If you can, avoid wearing a belt, as it can impair the clear lines you are seeking to present. You might put your jacket on towards the end of a performance to suggest a ramping up of the seriousness.
It’s a valuable addition to any wardrobe because parts of a three-piece suit can be mixed and matched with other clothing from time to time to make a different impression. Sometimes, the jacket matched with jeans and boots can maintain a sense of high-end style while giving off a very different vibe. Carefully accessorizing through your choice of tie or cravat can add a different twist to the impression that a quality three-piece suit will always make.
Incidentally, with all the options already mentioned, it can be worth considering becoming the owner of a pair of three-piece suits, thus increasing greatly the variations which could be part of your wardrobe.
