Looking like a millionaire without breaking the bank is simpler than you think, just follow these two rules:
Stick to basics & stay away from transitional trends. Classic styles are more popular nowadays among the elite because unlike the past, designer trends have gone global. What you see in fashion shows or runways is available to the masses in no time at any of the large affordable fashion retailers such as Zara, H&M, F21 or TopMan. Those with a lot of money don't fall for cheaper copies of designer clothes. Instead they invest in better quality of basic items that will remain relevant.
If you don't have the money to invest in labels or expensive designer clothes, look for classic items that can create a more polished look together.
Less is more. Choose wisely what you want the focus of your outfit to be. For instance sometimes you want a tonal (same color) outfit with a pop of color. The key is to not over adorn what already looks good.
As Coco Chanel once said before you leave the house, you should look in the mirror and remove one accessory.
