Confidence Is Key

Most, if not all, fashionistas in this world have one thing in common; Confidence. The confidence that says "I look good in everything that I wear."
You have to be confident that you will look good in the outfit that you put together. You can have the exact same outfit as Beyonce, but the lack the confidence to make it look good as she did. 
You also have to be fearless. Don't be afraid of what others will think about the outfit that you put together. Wear it with pride, and your confidence will do the rest.
When you step out of the house, let your confidence demand the attention you deserve.
