To protect the people of God from the corrupting influence of the world, as well as to promote physical and moral health, the dress reform was introduced among us. It was not intended to be a yoke of bondage, but a blessing, not to increase labor, but to save labor, not to add to the expense of dress, but to save expense. It would distinguish God's people from the world and thus serve as a barrier against its fashions and follies. He who knows the end from the beginning, who understands our nature and our needs,—our compassionate Redeemer,—saw our dangers and difficulties, and condescended to give us timely warning and instruction concerning our habits of life, even in the proper selection of food and clothing.

It removed the tight corsets, which compress the lungs, the stomach, and other internal organs, and induce curvature of the spine and an almost countless train of diseases. Dress reform proper provided for the protection and development of every part of the body.[For the reasons why this style of dress is not now advocated, read Testimonies for the Church 4:635-641.] ...
