All black and professional
Business casual, or high-trend fashion. Depending on the position you are applying for. If you are being hired as a Bra Specialist, or Sales Associate think about business causal attire with a flare of current fashion trends.
I would describe the dress code as business casual, a pair of slacks, a blouse and a blazer with some sort of simple fashion ankle boot would be an ideal outfit for an interview at Victoria's Secret.
All black, and professional attire. Nothing short (skirts, dresses, crop tops, etc.)
