Can a woman be modest and still attractive?

Short Answer:

Yes.

To explain, sometimes the most-beautiful women physically are the nastiest pieces of work, especially as their beauty fades. In contrast, a modest, nice and compassionate nature leads to an inner beauty that does not age. Don't follow appearances and confuse attractiveness with immodesty. Many a woman who has been dumped for someone less-attractive has said "What does he see in her?"
