A grand wizard's robes needn't be too flashy. Thick, loose cloths with vibrant colors and some magical adornments are all they need. Hats are optional, but what kind of wizard doesn't have a cool pointy hat? Oversized sleeves and loose fitting robes allow our wizard all the mobility they need to weave their magic. To add a bit more elegance for a wealthy wizard, I recommend adding "fur lined clothing" to your prompt. It's a subtle change but gives our wizard a more royal appearance, and keeps them warmer in cold climates. In some prompts, I've noticed the lora neglects to add fitting clothing to our wizard's legs. "oversized pants" fits well in my opinion, but you can also try any combination of "legwear, bottomwear, fully clothed," or just allow their legs to breathe. The robes cover most of their body, but it was a minor nitpick I had with some of my generations. Experiment a bit, and have fun.
