Some Christian ladies have chosen to be dresses/skirts only. If you are not dresses only, then you may find yourself wondering why some ladies do this. This article is not at all exhaustive, but will strive to chip the surface, and show you a few of the reasons why...
1) Women are called to be submissive to their husbands:
Wives, submit yourselves unto your own husbands, as it is fit in the Lord. -Colossians 3:18
One of the ways to outwardly show submission is via how one dresses. Think of it this way - people who work outside of the home often have certain ways they dress for their jobs. The way they dress shows not only their job (uniforms, for example) but may also show their seniority. In the home, the wife wears a dress, and this is just one of many things that outwardly helps to reveal her submission to her husband.
Notice also that the above says that wives are to submit to their own husbands. In every instance in the Bible, where it discusses wifely submission, it always stipulates to one's own husband. Nowhere does the Bible state that women are subservient to men. Women submitting to men, is always in reference to a wife, to her husband. It is a familial authoritative order, keeping with the mystery spelled out in Ephesians chapter 5.
2) Women and men are called to dress differently. Men are to wear man's clothing, and women are to wear woman's clothing:
The woman shall not wear that which pertaineth unto a man, neither shall a man put on a woman's garment: for all that do so are abomination unto the LORD thy God. -Deuteronomy 22:5
If you see someone from behind, and they have long hair, and are wearing a dress, then you'd likely assume that person is a woman. Women should wear clothing that shows, without a doubt, that they are female.
3) Women are to be modest, and have a meek and quite spirit:
Whose adorning let it not be that outward adorning of plaiting the hair, and of wearing of gold, or of putting on of apparel; But let it be the hidden man of the heart, in that which is not corruptible, even the ornament of a meek and quiet spirit, which is in the sight of God of great price. -1 Peter 3:3-4
Notice the above verse doesn't state how a women is to dress. It doesn't say how she is to dress. Instead, it states what she is to focus on, and what she is not to focus on. The modest Christian woman is not to focus on fancy hair styles, jewellery and accessories, and expensive, fancy clothing. Rather, she is instructed to focus on her inner person, and make sure she has a spirit that is modest.
4) Women are to be adorned in modest apparel:
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 -1 Timothy 2:9
The Greek word for "apparel" in the above verse, is "katastolē," which is a feminine noun, and means "a garment let down, a dress." You can look this up for yourself here. Notice also, that we again see that the important part is that the woman is adorned with shamefacedness - a modest attitue, and sobriety - not being under the influence of anything that alters her mind, and could distract her from Christ. Again, we see the above stating that she is not to focus on fancy hairstyles, jewellery, or expensive, fancy clothing.
5) Christians are to let their light shine. While that means being Christian in behavior and conduct, it also includes appearances:
Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven. - Matthew 5:16
Avoid even the appearance of evil. This means not doing things that appear wrong, or going places or participating in things that can appear evil. This also includes our own appearance:
Abstain from all appearance of evil. -1 Thessalonians 5:22
Lastly, Christian women may choose to be dresses only, to be more set apart from the world:
Ye adulterers and adulteresses, know ye not that the friendship of the world is enmity with God? whosoever therefore will be a friend of the world is the enemy of God. - James 4:4
They are of the world: therefore speak they of the world, and the world heareth them. We are of God: he that knoweth God heareth us; he that is not of God heareth not us. Hereby know we the spirit of truth, and the spirit of error. -1John 4:5-6
WARNING: Being dresses only as a work in order to get into heaven, or just for the purpose of appearing pious and religious to others is no good. Christian women who are dresses only should understand this is a heart issue:
Let the wicked forsake his way, and the unrighteous man his thoughts: and let him return unto the LORD, and he will have mercy upon him; and to our God, for he will abundantly pardon. For my thoughts are not your thoughts, neither are your ways my ways, saith the LORD." -Isaiah 55:7-8
For the word of God is quick, and powerful, and sharper than any twoedged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart. -Hebrews 4:12
And the Lord said unto him, Now do ye Pharisees make clean the outside of the cup and the platter; but your inward part is full of ravening and wickedness. -Luke 11:39
NOTE: Please keep in mind that the way you dress is not a salvation issue. The Bible is clear that there is only one way to heaven, and that is via believing on Christ, Who died on the cross to pay for our sins, and Who rose again, three days later. Also keep in mind that wearing dresses is a public issue in the general sense. If you are exercising, or doing an activity that clearly cannot be done in a dress, then please wear the appropriate clothing.
