Walaykum salam, Make her a nice cup of masala Chai, sit down and tell her ''darling - pleasing society and seeking honor from them is not the way of success. Pleasing each other is better and my pleasure is in pleasing God. So please me by being pleased with my pleasant sunnah clothes''. Everything will be 'pleaseful' then. Bro, jokes aside and to be honest. These things you cant be advised over the forum. Such things you should be able to sort out amongst yourself without seeking religious expertise. When a wife becomes disobedient and transgresses then the matter becomes serious and could warrant religious advise. Otherwise if your wife wants you well-groomed and feels sunnah clothes dont make you look as good as she wants you then I mean you can always sit and discuss with her and resolve differences. People will give you a million advise and leave you confused. YOu might end up with really silly advise over a forum like 'divorce her' which I am not surprised has already been conveyed.
