Classical Outfit ideas?

I have been scanning the web for casual classical outfits that usually follow conventions, they mainly show young females with big long dresses with a colour such a yellow or a light blue.

This dress really could portray a young female that enjoys classical music, it would also help my target audience, because they will see a teenager with an instrument. This above all will be good for a teenage magazine cover as my target market will be able to recreate it! Which could appeal to them more.
