The Fit of a Blazer
Generally, a blazer should fit like a suit jacket, though some men prefer for it to fit like a sport coat but other than that nothing is special here and all standard rules such as the proper sleeve length apply to the blazer as well. In terms of canvas or shoulder padding, most double-breasted blazers will have a more structured canvas and some shoulder padding, however with the popularity of the Neapolitan jacket, you will now find more unlined blazers with little to no shoulder padding and very soft interlining. As always, there is no objective right or wrong: the only thing that matters is what looks good on you and makes you feel good.
Below Are Few Fabrics For A blazer
Navy Serge – The Classic For A Blazer
Navy serge is a worsted wool that is probably the most popular fabric choice for a blazer. Usually made of merino wool, it has a characteristic twill structure and in my experience it is phone to get shiny in areas of frequent friction. For this reason, be careful when ironing or dry cleaning because too much heat or direct contact with the iron will also make it look shiny in an unpleasant way. If you want a deliberately shiny blazer, look for a wool mohair blend; that looks much more sophisticated than a worn-out serge.
Hopsack For A Blazer
Hopsack has an open weave structure that will immediately add more texture to your outfit, but it is also much more prone to pulled threads. So if you have children, pets or often come in contact with items that could pull a thread, hopsack may not be the best choice for you.
Flannel For A Blazer
For winter blazers, a true wool flannel is ideal if it’s not going to be in heavy rotation. If you plan to wear the jacket frequently, opt for a worsted flannel so you can get more wear out of the blazer. Both will wear a bit warmer and the flannel nap will make it more suitable for fall & winter ensembles.
Cashmere or Vicuna
For a more luxurious alternative fabric in winter, choose cashmere or vicuna. These luxurious fabric will look and feel beautiful, though they will cost many times more than a traditional blazer. Then again, versatile pieces are usually the best place to invest anyway.
Fresco or Linen
If you live in a place where it is always warm, you should look into linen or fresco blazers. Many men don’t like the wrinkled look of linen; others simply embrace the look. If you are not one of them, I recommend fresco wholeheartedly.
A Blazer Details
AS mentioned before, you have plenty of choices for buttons. While gold and to a lesser extent silver buttons are most common, buttons in white or grey mother of pearl can look just as stunning as light-coloured horn buttons. At the end of the day, it is entirely up to you what kind of buttons to wear, so think about it and select what feels right to you.
