A blazer or suit jacket is a versatile item of clothing which you can wear on casual to formal occasions. It is a must-have clothing item regardless of season and location. This article will provide key information in buying, choosing and wearing a blazer.   First, let’s talk about buying a blazer. If it’s your first time to buy one, then consider the dark navy blue fabric. Your second color choice would need to be dark charcoal tone. These colors are flexible. They can be worn in different occasions. In terms of fabrics, choose wool. Wool is a durable choice. It will give you comfort and warmth. However, it’s important to consider pricing. There are cashmere and 100% merino wool options that are very pricey. There are also wool and polyester blends that might work out to be a more practical option. When you go shopping for a blazer, wear a jacket. Try on blazers while you have a jacket on. Most likely, you’ll be wearing several layers with your jacket. Focus on what will make you comfortable so you can carry your outfit well.   Now, let’s talk about choosing styles. The most important factor in choosing the style is the “fit”.  You need to pick a style that fits your body well. The sleeves of your blazer should be half an inch shorter than your dress shirts. It should leave some room for your dress shirts cuffs to show.  Your suit jacket needs to have good-sized vents. There are two types of vents, single center (back side) and double vents which are located at the side seam. If you are slim, single center vents would be better for you. If you have a big built, then choose double vents for more comfort.  “Lapels” or the flaps around the chest are another item of style. Medium-sized lapels are the safest choice. Choosing between single or double-breasted jackets depends on your built and height. If you are tall and lanky, double breasted jackets are recommended. The horizontal position of the buttons will create an illusion of width and would complement your body style. If you are big and short, buy a jacket with more than 2 vertical buttons to create an illusion of length.    “Dressing well” means wearing the right clothes at the right situations. If you have to attend a semi-formal afternoon meeting, you can pair your navy blue jacket with a khaki or white pair of pants, tie and dress shirt.  If you have to attend a formal corporate meeting, you can wear your jacket with matching pants of the same color, contrasting dress shirt color and complementary tie. Formal occasions also demand polished, leather shoes.  For a casual dinner date, you can wear your jacket with dark jeans, dress shirt. You don’t have to wear a tie.   In summary, picking the right blazer means being smart about the price, the fit, the style and the occasion.
