Finding your style of clothing is a matter of action and patience. Indeed, it is a building process that takes years.
This construction passes by regular actions and a fierce desire for discovery. To build your style, it is necessary to get out of your comfort zone. It is a permanent back and forth mechanism (hum, hum...): one day you discover a garment or accessory that suits you perfectly and the next day you make a stylistic "mistake" that you bitterly regret 2 years later by looking at your family photos...
In short, you have to act and take risks to find your style. In fact, you will have to test many pieces and sometimes even complete looks to see your style take shape. Little by little you will instinctively feel if the clothes fit you and make you look good.
In men's fashion, good taste is the set of dress rules accepted with regard to a given style and era. Thus, the good taste of the Twenties is different from the one we cultivated in 2010. For example, the cuts of 1920 were looser than those of 2010 on the level of the pants whereas today in 2018 one notices a return of the straighter cuts. The 20's are back!
Knowing the right length for a pair of pants, knowing which colors to match together or which fabric to choose for a formal shirt, are all elements that need to be known and are part of good taste.
