Would be double major or minor be more useful for me with managerial econ?

I’m transferring in next fall as managerial econ major and I’m also interested in PR and the working in the fashion retail industry, do you think minoring in textiles&clothing and comm would help me or just waste my time? or I was also thinking double majoring in just comm and then taking a few classes from the textiles major? bc I pretty much have the pre reqs done for that major already.
I’ve heard from people that managerial econ is a time consuming major at davis so I was a bit worried that I might end up overworking myself when I transfer.
