This prom season high school girls will spend weeks struggling to find the perfect dress – will it be gold metallic, ravishing red, bright white or the hottest color? The dress is just the beginning, KNOE 8 News reports. Prom costs for girls also include the perfect shoes, jewelry, a salon visit and a boutonniere. Expenses for boys can include tuxedo, accessories, shoes, vests, ties, hair, prom tickets, dinner, corsage, photographs and transportation. LSU AgCenter family economist Jeanette Tucker cites a Sallie Mae study that revealed about half of high school senior girls shop for two or more weeks to pick out their dream dress and half of senior boys spend two or more weeks deciding whom to ask to the big event. … Two weeks spent planning for the prom is significant; however, when it comes to college, nearly half of the high school seniors surveyed spent five or fewer hours learning how to pay for a four year degree, Tucker said.
