To adapt from Lloyd Bentsen,
"Sir, I've dated hot girls. I've known hot girls. I'm friends with hot girls. She, sir, is not a hot girl."
At least, not with regards to that beyond fugly hair. As kay said; that girl would look way better with dark hair. She's not horrible, but it's because the rest of her manages to compensate for that hair choice. This isn't a 'good girl' thing or a 'bad girl' thing, a 'clubbing' thing or a 'non-clubbing' thing. Streaks, I can work with (and some are nice). Girls who totally bleached their hair? As a general rule, pass.
There isn't a single girl I've ever seen or met with bleached hair, who wouldn't look immensely better without having done so. Goes for guys too, btw. It just makes you look fuggin' retarded, no offense to anyone who's bleached their hair
I'm suddenly reminded of a friend of a friend who I met twice. She's a 'bad girl', as Ghaleon might put it; hard clubber with a harder body, streaked hair, got some tats, belly rings, very suggestive clothing, etc. The first time I saw her, I swore she was the hottest girl I ever met. Second time I saw her, she bleached her hair and, IMO, looked like a fuggin' freak.
