AITA My [28M] Wife [27F] Got Offended While I Was Trying to Reassure Her

This morning, my wife was getting dressed to go speak at a career panel at her old high school. She was panicking about what to wear. She asked me to use a Tide bleach pen on a white blazer to get a stain out, which I did, but then she realized it looked too “ostentatious” and decided against it. Then she realized she didn’t have anything except a grey blazer and black dress pants and a green top. When she came downstairs to show me her outfit, I enthusiastically told her that she looked good, but she wasn’t convinced and said that the pants and blazer didn’t match very well. Then I tried to compliment her again and then she asked me not to lie to her. I tried to be as constructive as possible and said, “don’t worry, we can look into getting you matching pants/blazers soon,” which I think went over well. Then I made her a coffee and she started to leave. But then when she was walking out the door, I told her, “remember, they’re there for what you say, not for how you look,” and she just stared at me like I cut her with a knife. As she was walking to her car she turned and said, “geeze, I didn’t think I looked THAT bad…” and walked away. I tried to clarify, but she wasn’t having any of it.

I was just trying to reassure her that the students wouldn’t judge her for her clothes (a tad wishful, I suppose) and would only care about what she has to say, but it appears my message was lost. Am I the asshole?
