Sara Jessica, please take this in the spirit that I mean it (kindly), but I can tell you this from the POV of having been there that nothing will ever be enough until full and complete acceptance and even then, your wife's full participation still would not be enough. Maybe it has to do with the need to be seen and heard and believed and respected by everyone. It's the wish or the need for a multi-faceted life.
My SO also dressed at home for years. When she found an accepting partner in me, she wanted to go out and she did, alone and with me. Eventually she wanted to make friends who were separate from me. She wanted her own friends, her own experiences in which I was not involved and which were deeper than interactions with the obligatory politeness and niceness of SAs and nail techs. This is when she stopped dressing at home and when I suggested a nice dinner at home just the two of us, she kinda stopped being interested.
A wife's approval is only one step in the process.
