I need daily casual wear advice please
So I watched a video and it was along the lines of “…if you wear T-shirt’s with jeans and tennis shoes, you don’t wanna be that guy…” and I felt super called out 
I can’t go out and buy a bunch of clothes right now, but I want to come here and ask for some advice on cause wear. If I dress up too much, my wife gets upset because she feels out dressed or she thinks I’m looking for something
I just wanna dress nice.
So what is a step below business casual, but isn’t just “tshirt and tennis shoes” because that’s all I have right now. I’ll shop later just coming here for what to shop for. I live in north Texas USA for weather inspiration. I know it’s hot, but I do not like wearing shorts if I can help it. I will, I just prefer jeans (or a different long pants if anyone knows any for hot weather)
