One point to remember is your wife is suffering form the after effects of her stroke , she may secretly be thinking where will I be if it happens again but much worse ? Seeing you depressed about your dressing is now not her priority , her answer was an obvious one in the circumstances , she may not get better no matter what clothes she wears but you can change your situation simply by dressing or not . She accepts enough so it's up to you to decide whether you really need to dress or not. I doubt she is going to make a big issue of it which ever you choose .
The other point is she could be more envious of you than she's letting on , she can longer slip into nice clothes because of her slight immobility and you can still pick and choose .
