In at least one source I have read that in ancient Greece, it was the sign of an unmarried woman to wear a belt on her dress. When she married, her husband removed the belt, and she then wore a dress w/out belt. (The belt itself was sacrificed to Artemis.) Amazons did not marry - they considered marriage a thinly-veiled form of slavery. In that context, requesting that Hippolyta remove her belt would be a kind of sexual harassment. Which explains why an Amazon wouldn't let a man remove her belt, and why Hippolyta resisted Heracles.
