I have no sense of style. None. Absolutely zip.. on my own I come up with the worst combinations of clothes/whatever.
Which is why I tend to trust things that say "everyone else does it this way/uses this". It's stupid that I follow that trick, because it could be an outright lie.. but I can't help it.. I'd rather take my chances than come off looking like too much of an idiot
Also, if I am at the store and I see a bunch of brands for the same product, I tend to grab the one that had the best ad on TV.
