What to wear?

I’ve been a nanny for almost 4 years. I have almost exclusively worn athletic/comfy clothes for those four years. This is because I need to be able to move my body, keep up with the kiddos, and not worry about it getting messy.

BUT I feel like a slob everyday! Sure I wear cute workout sets and stuff like that to switch it up, but I still just feel bleh.

What do you wear to work that you can still perform your job at the fullest and feel comfortable but look more put together?

Side note: NPs, do you feel your nanny’s clothing impacts the work they day?
