If you want to know God's will for you and your daughters in this matter, even if it isn't God's will for another woman, you're directed by the Scriptures to go to your husband. It doesn't matter whether or not he is sure. Your going to him will prompt him to study it out.
This is just not true. God's will is not revealed to women through their husbands. Certainly dress for their children should be a joint decision, but the husband's word does not need to be final. In fact, in many of these cases, men are not in the best position to do so.
