What colors to wear?

Firstly I would say choose always colors that make your eyes sparkle. Some colors just fit better with our skin tone, hair and eyes. If you have not found this kind of color, you can try different types of colored clothes and take a good look at yourself, I think the answer is not so far away.
Suggestion that may work on blond hair and fair skin - light blue, ocean blue or turquoise.
With really fair skin and light hair, I do not recommend wearing clothes that are only white. Combine white with other colors.
If you have darker skin you can surely wear violet or pink. Green is also an option for people with darker hair or skin.

As you might understand I recommend these colors of course for the Spring!

Prada 2011 Spring collection has a lot of colors and stripes, if you are not so courageous, use smaller amount of color maybe with one yellow scarf you can already make yourself special!
