Marriage or any relationship is a team effort. It seems the needs of relationship are not being met, support of the spouse with new clothing choice, maybe she is confused about kilt wearing. He may not be explaining his desire for new wardrobe adequately. Quid pro quo, you must know what one can bend on and what you can not.

My wife saw I was interested in kilts and demanded I order one. Now she enjoys me being happy and admires the swish. Our children are split. My daughter gently teases but realizes I'm old and humors me. Our son is a little more into eye rolling but knows it too late and will not join Kilts Anonymous.
We rarely sit down and talk about dividing up tasks or whatever. As things happen, the person best suited for the task steps up and if needed advised of other viewpoints for resolution.

It took forever to find someone to put up me. And after all these years she still puts up with my ways.
