I'm a Coach and an English, and often those two things cross paths. Some of the first advice I received as a Coach was to make sure that I always dressed appropriately.
Not Appropriate: Old College Sweats, Boyfriends Sweats, anything that's been washed longer than you've been alive.
Appropriate: Sweat Suits, School Affiliated Sweat Top with Jeans, Fitted Workout Jacket with Khaki pants.
|So appropriate, and coordinating.|
Really it's not that hard, but you'd be surprised what some Coaches wear and think is a respectful way to present themselves. Even on our busy schedules a little care goes a long way.
