You have a point. But you're also seeing these girls on the beach, not all dolled up for the disco. Also when on vacation and having a good time its easy to think a girl who is regularly below you're standard of pretty or a dime is fly because you're having a good time, drinking n whatnot. Most of these "dimes" look nothing like they do at home au natural as opposed to when going out at night. Same goes worldwide. Not all women have natural beauty its just the lengths they go to appear beautiful that gets men confused about how sexy they really are.
