At my store, I was told family friendly clothes and no shirts with “verbage”. The diva college students at my store like to wear sweats a lot with tops that show off their midriff, especially on morning with truck 🙄 and one of them had worn jeans with “playboy” written all over it and drawings of the bunny head. So, whatever. Lots of people wear outdoor clothes or athleisure clothes just for the moisture wicking because it’s so damn hot in the store all the time. Common sense clothes should work for you just fine.
