The only direction Christian men and women alike are given is to be modest in dress...it's not the outward appearance that is important, but what's on the inside that matters...
"Likewise, the women should adorn themselves in appropriate dress, with modesty and soundness of mind, not with styles of hair braiding and gold or pearls or very expensive clothing,
but in the way that is proper for women professing devotion to God, namely, through good works." 1 Timothy 2:9,10
"Do not let your adornment be external—the braiding of hair and the wearing of gold ornaments
+ or fine clothing
but let it be the secret person of the heart in the incorruptible adornment of the quiet and mild spirit, which is of great value in the eyes of God." 1 Peter 3:3,4
