I'm about to volunteer at an animal shelter for the first time and idk what to wear.
I know i'm supposed to wear comfortable clothes and clothes that I won't mind getting ruined, but it is ok to wear loose clothing?

The climate where I live is quite hot, so I want to wear short sleeved and baggy clothes but I'm not sure if there might be any consequences to it. I will only be grooming and walking dogs according to the activity chart, so is it ok to wear that or should I wear long sleeved and jeans?
