My daughter is in AF BMT and would like for me to wear my dress blues for her graduation. Is this appropriate now that I’m retired?

Why not? You are retired and as long as they fit well and you don't start going around giving orders you should be good. My last 'good' uniforms were the old Class B Khaki Uniform, Class A Dress Greens, Dress Blues.

I'd say as long as the uniform fits properly and you can adhere to current Dress and Appearance standards (AFI 36-2903), go for it!!

Wish I could still wear my uniforms but unfortunately, the gremlins got into my closet and shrank my service dress two sizes smaller! lol

SMSgt Bill Gates Go in uniform and let her show you off! Great she's proud of her dad.
