Hawt = A late 1940's and early 1950's acronym for "Having A Wonderful Time."
Now the word is used on the internet as slang for something reeeeally hot.
Jessica Alba looked utterly chic whilst en route to the Ralph Lauren SS14 during New York Fashion Week. Wearing a long baby-pink Ralph Lauren chiffon ballet skirt paired with a simple black cropped jumper, accessorised with a patent black bag and a classic chignon hairstyle, the actress looked part Audrey Hepburn, part Carrie Bradshaw – the perfect combination of elegant and quirky cute. So hawt.
