Re: mother in laws common sense?
^ 100% agree with this!
My FMIL also gives me things that I don’t like and don’t want (yes, I have gotten clothes that I find hideous and/or doesn’t fit me at all). I always graciously accept it…and then put it away. I have never worn any of her clothes. Heck I even got a watch last time that I never plan on wearing (I don’t wear watches).
Unless you live with your in-laws and your MIL actually picks out your clothes when you go out…not sure how you’ll be “forced” to wear them.
As for the $$…don’t worry about her money. Let her spend it however she wants. Throughout your marriage, there will be many situations where you’ll need to speak up and get things your way…in the “big picture”, this is not a big deal. For you to mention something and take the risk that your MIL gets offended by it and it negatively effects your relationship with her…it’s not worth it.
