All you need to know for a top-notch physique
The size is essential: If there is one thing that men could learn to be better dressed and look better, it is to choose clothes at their size. Half of the people I meet in Paris are dressed 2 sizes too big. Learn how to choose clothes that fit you, so that it enhances your figure. And if you don't know, call a professional, it will cost you much less than buying unsuitable clothes.
Keep it simple: Ideally, you need to redo your wardrobe so that it enhances you, but not too much. Do not repeat the usual trick of men who discover fashion: to pass without transition from the mop stage to the stage "I'm dressing expensively now and I want it to be seen".
Example: Avoid bling bling jewelry, rings and rocker belts unless you are 20 years old and playing in a band. It's better to do it in small touches. First a basic but elegant wardrobe. Then a progressive accessorization to enhance it. Don't confuse the main and the accessory.
Learn to see the "casual" in another way: You can be elegant without being in costume. Casual doesn't necessarily mean jogging sneakers and Decathlon t-shirts. Take a look at the casual-chic article!
