Business clothing

I feel super hurt. I probably am being emotional because of hormones, but my boss is completely insensitive. I went for a promotion, was told I don’t dress nice enough.... wtf I feel huuuuge and I have had to buy new things I immediately started crying. I am already a store manager a d have been doing this job for 5 years. I just don’t understand why you would say this to a pregnant women. I just don’t understand why she is bagging on my clothing. Do you think it’s inappropriate? Or not nice enough, yes the shirt is a little wrinkly. I need help I don’t know how I should be dressing, any suggestions on business professional clothing?
