"Could I do a walking tour in this?"
The essence of Natural style is relaxation, freedom, and uninhibited movement. If an outfit is something you could wear for a walking tour of a hilly European city, it probably has a lot of Natural. Clothes you could comfortably take a nap in are also usually Natural.
Romantic fabrics often beg to be touched. This absolutely relates to the fact that Romantic style is the embodiment of feminine sexuality. If you can't wait to run your fingers across a fabric, chances are it's part of a Romantic ensemble.
Dramatic ensembles are avant-garde, outside the norm -- and we humans are naturally intimidated by stuff that's outside the norm. If an outfit makes you feel like taking a step backward, it likely has a strong Dramatic influence.
Ingenue style is an archetype of traditional girlishness. Almost anything that's Ingenue looks as if it emerged from a Norman Rockwell painting -- or from the closet of Sandy in "Grease." (Before her makeover at the end, LOL!)
Gamine style is boyish. If an ensemble looks like something a little boy could conceivably wear to school without raising eyebrows, it probably has a lot of Gamine.
That may sound ridiculous, but Ethereal styles make the wearer look as if she can take flight.
Whether formal or casual, Classic ensembles always look conservative and rich. In a Classic outfit, you'd never be embarrassed to run into the C.E.O. of your company. There's never anything attention-seeking, objectionable, or out of place in a Classic look. You're above reproach.
