What does summer really mean for kids?

The whole world of fashion is now working on the next spring summer collection, for 2010.
Researching on trends, colours, fabrics, shapes, and ideas.

While all these people working, myself included, I came up with a thought:
we are creating the most innovative and cool summer fashion for kids, but what does the word summer really mean for them? And mostly, do they really need all these fashionable clothes?
