I once dated a guy who was always full of compliments (overly so tbh) until one evening we were at a bar and I was wearing a dress with thin straps, with my bra straps visible.
When he leaned in and said, "now this, I don't like", gesturing to my straps, he got the sharp end of my tongue and I remember being (what felt at the time) disproportionately angered by his comment.
I was about 22, he was 10 years older, and I ended things soon after. The incident always stayed with me though, and it's only years later, reading this comment, that I realise that I was entirely justified in my anger, and that it was absolutely a misogynistic red flag.
