The definition of elegance is:
"Refinement, grace, and beauty in movement, appearance, or manners."
For you, elegance could be walking tall and enjoying your body. It could be wearing pearls, it could be wearing high heels. Maybe it is choosing the champagne over the $6 wine. Elegance can be an array of things.
The energy of elegance and money are very similar. Elegance makes you feel graceful and beautiful with minimal effort. When you are generating money, it is almost effortless.
