I used to think that, but why do I see so many non-Chad men in relationships? I am planning on writing a rather long and detailed post refuting a lot of Tails' common themes and criticising his methodology. But regarding fashion he's partially right. Toilets have strong group preferences and are way more visual than men in selecting (how many men ONLY want a hot Goth GF? And how many want just ANY toilet?), Toilets also filter by groups. This is also why no amount of attractiveness will save a Chang or Tyrone if she's only into White men and why no amount of height is going to save a man's chances if she's only into muscular men.
Stylemaxxing does help, but it only helps if you have the face to pull it off.
