It seems to me that invisibility is the required provision of elegance. Elegance ceases to exist when it is noticed.

The famous Florentine elegance, which attracts tourists to the shops on Via Tornabuoni and Via della Vigna Nuova, is characterized by austerity of line, simplicity, economy of effect.

Elegance is good taste plus a dash of daring.

The only real elegance is in the mind; if you've got that, the rest really comes from it.
