God's people should practice strict economy in their outlay of means, that they may have something to bring to Him, saying, “Of Thine own have we given Thee.” Thus they are to offer God thanksgiving for the blessings received from Him. Thus, too, they are to lay up for themselves treasure beside the throne of God. MYP 313.1
Worldlings spend upon dress large sums of money that ought to be used to feed and clothe those suffering from hunger and cold. Many for whom Christ gave His life have barely sufficient of the cheapest, most common clothing, while others spend thousands of dollars in the efforts to satisfy the never-ending demands of fashion. MYP 313.2
The Lord has charged His people to come out from the world, and be separate. Gay or expensive clothing is not becoming to those who believe that we are living in the last days of probation. “I will therefore,” the apostle Paul writes, “that men pray everywhere, lifting up holy hands, without wrath and doubting. 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.” MYP 313.3
Even among those who profess to be children of God, there are those who spend more than is necessary upon dress. We should dress neatly and tastefully, but, my sisters, when you are buying and making your own and your children's clothing, think of the work in the Lord's vineyard that is still waiting to be done. It is right to buy good material, and have it carefully made. This is economy. But rich trimmings are not needed, and to indulge in them is to spend for self-gratification money that should be put into God's cause. MYP 313.4
It is not your dress that makes you of value in the Lord's sight. It is the inward adorning, the graces of the Spirit, the kind word, the thoughtful consideration for others, that God values. Do without the unnecessary trimmings, and lay aside for the advancement of the cause of God the means thus saved. MYP 314.1
