Parents clicked away with digital cameras at one pre-prom gathering, then later a row of security guards searched purses for alcohol, cigarettes, drugs – and gum. Nowhere more than on the dance floor was it more evident that proms of the 21st century are far different from just a decade ago. Guys and girls danced provocatively to the beat of the music as if plucked from an MTV video. Another milestone for these teens, the first to attend a West Ranch prom.160Want local news?Sign up for the Localist and stay informed Something went wrong. Please try again.subscribeCongratulations! You’re all set! SANTA CLARITA Tresses were curled, teased, ironed and hairsprayed. Flawless triple coats of mascara, bronzer and blush glazed their faces. Some had traveled as far as Las Vegas or Santa Barbara to buy the perfect dress, while a few procrastinators went shopping that day. The gowns spanned every style, from princess froth to barely there lacy numbers. Teenage girls across the nation are primping this time of year for the quintessential event of a high school career – the prom. Many will spend hundreds to attempt perfection and some parents footing the bills will go along in hopes of making the night unforgettable. At West Ranch High School in Stevenson Ranch, boys and girls alike were the height of fashion during their prom last week at a Hollywood backlot. This was a first for these kids – the school is just three years old, and this is the first year there are juniors. Next year, it will be a junior-senior prom. Some coordinated every detail of their outfits – a white suit with a colorful tie and matching sneakers was a popular look for the West Ranch guys. One teen even coordinated a brown-and-orange baseball cap to his same-colored suit – and matched his date’s sequined dress. Many girls went to great lengths to ensure their dresses were one-of-a-kind. One girl returned a dress twice, then arrived to find another girl at the prom with her same canary-colored gown. Some chose gowns that bared their midriff and dropped down to there in back.
