Sounds like my coworker. She's not that attractive, but moreso because she takes so little care of herself and presents an image that drives people away. Her profile picture is straight hair died red (red in nature always means danger), horned rimmed glasses, no makeup with pale skin because it looks like she never goes outdoors, in a t-shirt. Oh and she has 5 cats.....in a single bedroom apartment. Can you imagine the smell? Oh and no social skills: she often takes comments not directed toward her as insinuating she doesn't know a topic and then over-compensates.

I'm not particularly hung up on makeup or looks, but there are looks that say, "I care about myself" and looks that say, "I have zero self-esteem". Low self-esteem people are dysfunctional in many ways. They're essentially project boats. You're going to dump a lot of time and money into them with little return on your investment.
