Most Helpful Guy
Even your eyes or your hairstyle can make you unattractive. But it differs for everyone. To me, looking like a genuine slut (black skin coat with red mini skirt and red high heels, for example, with some pink involved and blond hair) is a red flag, while for others, that's the ultimate perfect ideal. You can't really know.
But for one certain thing, being bitchy and needy and whiny is a definite off.
