In 'the importance of bing earnest,' what makes algy a dandy figure?i want to know also how wilde makes use of algy to show that people may be dandy

The Victorian Dandy is described as
a bachelor which has the following
characteristics:

a. Living above their
means

b. Over- preoccupied with aesthetics and fashion
rather than social responsibility

c. In Wilde's words "wake
up near 3 in the afternoon, dine at 5, then the opera, and go to bed near 3 in the
morning"

d. Surrounded by the likes, hating on anything
ugly, completely oblivious of human emotion.

Algernon
comprises ALL of those characteristics. Opulent, he has creditors running after him.
Excessive, his hunger and eating habits represent the way he lives life: Excessively and
always wanting more. Flamboyant, as he always expects the best champagne, the best
restaurants, and always dresses to the part. Immoral, as he leads a double life and does
not mind meddling in that of others. Fascinating, because he simply admits it and does
not care.

Post Note: Oscar Wilde was a
fanatic of the ideal of the Victorian dandy, and for this reason he ensured that there
was a dandy in most of his works:

In The Picture
of Dorian Gray, the dandy takes the shape of Lord Henry
Wooton

In A Woman of No Importancethe
dandy is Lord Illingworth.

In An Ideal
Husband, the dandy is Lord Goring.

Hope this
helps!
