I wear sneakers and jeans (I'm not a sweatpants person anyway), nice-ish shorts in the summer (jean or gray khaki). Usually hoodies (no need for a treat pouch then!), or t-shirts, and bait bag when needed. I hate putting treats in my actual pants pockets. Tank tops if it's super hot, and even then, only really when I'm running agility. I try to look somewhat decent with I'm with a client.
Oh, and I do have a vest that I wear on occasion, but it's a bummer because no one around here knows the training club (I got it with my club in TX, which has since disbanded anyway...). It's a puffy vest with nice, deep pockets hahahaha. I love it
ETA - My jeans actually fit me HAHAHA. But I'm a bit of a jean-junkie as it is. I LIVE in them.
And my hair is generally pulled back, but sometimes just part up in a clip or with a headband or something. I also ALWAYS have makeup on and carry around lint rollers so that I don't look like I wash my clothes in dog hair
