The look for fall: bombshell!

As Labor Day weekend approaches, the fall beauty buzz is spinning up to a fever pitch. Get ready to say "buh-bye" to the au naturel beach babe--the hot look for fall is pure bombshell.

For inspiration, we'll be looking to the screen goddesses of the 1940s and 1950s--think Rita Hayworth's sensual curls, Marilyn's sultry eyes, and Audrey Hepburn's flawless crimson pout.

Even though the thermometer tells us it's still very much summertime, this hot fall look is already rocking the red carpet on celebrities from Jessica Alba to Isla Fisher to Mischa Barton.

So if you're ready to make a big impression this fall, just keep three little words in mind: Va. Va. Voom!
