here a few tips to keep in mind:
Mix some feminine pieces with playful options to keep the look age appropriate and fun. Think sweatshirts and a youthful pearl necklace, sneakers with skirts, or ruffles with rain boots.
Girls of this age have developed their own interests and sense of style. Let it show.
Avoid things too glittery or chaotic. It just ends up looking cheap and tacky.
As always, blend colors, textures and patterns to give outfits more interest.
