Elegance

“A woman's dress should be like a barbed-wire fence: serving its purpose without obstructing the view.” -- Sophia Loren

Every woman should have atleast these five simple dresses in her wardrobe:

The little black dress  - for formal functions or dinners
A white floaty dress - For summers days, luncheons/barbeques
An executive dress-  for interviews or Business meetings
A long elegant dress - for a ball
A colourful dress - can be worn on normal days and make you feel young
 
Etiquette

Suits you

There's nothing better than your personal touch. It's good to compliment someone on their dress but not copy them. Instead, be inspired and chose what looks good on you. You'll be more confident when you know what's suits you.
