Women are to dress moderately so as not to lure men to sin. Waring cloth that is revealing can make men sin in their heart. Though if one sin in his heart we can know but God knows everything. Men are move by what they see and the half-naked women they see around could make them sin in their heart.
1 Timothy 2:9-10 In like manner also, that women adorn themselves in modest apparel, with shamefacedness and sobriety; not with broided hair, or gold, or pearls, or costly array;
But (which becometh women professing godliness) with good works.
