What do you think of the feathers from Sephora?

Click on this link to see the feathers, a href="http://www.sephora.com/browse/product.jhtml?id=P289009." rel="nofollow"http://www.sephora.com/browse/product.jh…/a The feathers clip into your hair as opposed to sew in feathers. This means I can take them out of my hair whenever I want. I'm 13 and I have dirty blonde hair, so I'm thinking of getting boho breeze (refer to link). Do you think that would look good for my hair type? Will it look to childish on me?
