He should dress like he wants except for weddings, funerals and any event that would get the two of you kicked out if he dressed wrong. Outside of that, it’s fair game and he’s earned the privilege.
okay if he’s alone but when we’re out he can dress like a grown up and i do the same courtesy for him. I’ve earned that privilege after being married over 40 years.
If he looks like a schlubby guy anywhere but a run to Lowes to get mulch.... no dice.
