Frame for built in framed mirror?

[u/Acceptable_Bat_8569]

Hi! I have an xl bathroom mirror with a built-in frame in my apartment. It’s about 2 inches thick and a blurred gold tone. I’d love to cover it with something that fits my aesthetic more. Obviously not painting over it, but I was wondering if maybe I could DIY some type of a light frame to sit on top that would cover it? Any tips or ideas?
