first of all sorry, but get the name right (it's kinda important) its Victoria's Secret (an apostrophe then an s after Victoria, and then there is not an s at the end of secret)
anyways you should wear a high-waisted black pencil skirt with a sassy, colored blouse tucked in, and a cute belt. (blouse color maybe like yellow, purple, or red?)
and wear some reasonable heels that are easy to walk in (you don't want to wabble into an interview)
OH and i know it's victoria's secret and all, but don't show too much cleavage. lol
