If I truly love a design feature or type of ensemble and feel pretty sure it flatters me, I won't be swayed by visceral negative reactions from others.
For instance, quite often when I post a pencil skirt and blazer look (or blazer and trousers) or when I express a desire for a suit, people on the forum will mention that they feel this is too "corporate" a look -- either for the occasion I've named, or for anyone with my lifestyle, or maybe just in itself. I got some comments like that when I wore a pencil skirt and a leather jacket on a trip. People felt it was too "dressy" or too "corporate" for a day of sightseeing, gallery hopping, restaurants, and theatre.
Well, that hasn't stopped me from continuing the search for my HEWI suit. Which I'd happily wear in similar circumstances.
If I'm unsure about something, though, I could be swayed by others' reactions. Especially if their reactions were not just general poison eye, but had to do with how it looked on me in particular.
Meanwhile, if I have a poison eye for something, I can be swayed in favour of it by updated stylings (to Rae's point.) Or simply by seeing someone wear it really well.
Or maybe simply by getting familiar with it!! In this case, familiarity may breed tolerance and even love. Sort of like an arranged marriage.
