Albert Barnes Commentary Esther 2:15

"Now when the turn of Esther, the daughter of Abihail the uncle of Mordecai, who had taken her for his daughter, was come to go in unto the king, she required nothing but what Hegai the king`s chamberlain, the keeper of the women, appointed. And Esther obtained favor in the sight of all them that looked upon her." — Esther 2:15 (ASV)

She required nothing - The other virgins perhaps loaded themselves with precious ornaments of various kinds, necklaces, bracelets, earrings, anklets, and the like. Esther let Hegai dress her as he would.
