HI Amelia, Good morning Mary, I love the dress you are wearing. Your hair looks great did you just have it cut! What a lovely smile you have!

In the U.S., we will start out with "You're looking well." It's general and covers most situations. Women will usually compliment another woman's clothes or hairdo. Men usually feel incompetent about clothes and hair, so they stay silent about such things.

Hi... in French we will say "C'est très bien" or "Je te/vous félicite"... etc...
