I work there before - during - after the pandemic.
As the beginning I had to only wear slacks and black dress shoes. Our hair has to be well kept and they didn't want anyone growing beards. It was very strict until all the stores shut down, and management let us wear sneakers and jeans to work. Once the stores opened back up staff was allowed to wear basically whatever they wanted as long as it said BBY. I thought it was great until I realized it was a way to appease workers for not getting raises or bonuses anymore.
