Nina Garcia offers you the answer to the question "What should I WEAR?"
There is ridiculous, that no women over the age of 29 should wear a skirt shorter than two inches above the knee. ( if you go to your son soccer's game you may were a micro-mini skirt with some knee-high boots). If you want to make a good impression you must know that it is made from: understanding boundaries, communication, social savvy and knowing thyself. Only after you understand what a good impression means, you'll understand the style language of every occasion and graced them with your presence...By the way...you must know that fashion is more close to the business world, then style witch is a thing that money can't buy :)
