Generally speaking, I'm a jeans, T-shirt and boots man but I do own an Armani suit, which gets a regular outing. It's nothing fancy - just a classic, well-cut suit with clean lines and beautiful tailoring. It's timeless and you can mix and match it with anything to dress up or dress down.
Those who think that in order to dress well it is necessary to dress extravagantly or grandly, make a great mistake. Nothing so well becomes true feminine beauty as simplicity.
Dress simply. If you wear a dinner jacket, don't wear anything else on it ... like lunch or dinner.
You can be the chicest thing in the world in a T-shirt and jeans - it's up to you.
My rule of thumb is to strike a balance by sticking to the classics and playing with color, texture, and print to give them a modern update. On any given day, I keep it simple with jeans or chinos and a comfortable dress shirt.
A stylish person, for me, is one who draws your eye without necessarily being showy; they wear clothes that are beautifully cut, flatter the wearer, and show that they are not impervious to fashion, but not a slave to it either.
People often think that the world fashion is so full of a certain pretense that it can't just be about going for something because it suits you and looks great, and it's nicely cut and is made of beautiful fabric. You know, if it has a bit of lightness and playfulness to it, then I think people just respond to that really well.
