So how are we to dress?  If I can't become a street grunge or gangbanger or whatever the current fad is then what? By the way I do not profess to be current on what is proper slang nowadays.  I will start with a familiar passage.  This passage is speaking specifically of tongues, but applies well to what we are discussing.  I Corinthians 14:7-8, "And even things without life giving sound, whether pipe or harp, except they give a distinction in sounds, how shall it be known what is piped or harped?  For if the trumpet give an uncertain sound, who shall prepare himself to the battle?"  So what can we say, if we do not sound and look different then who would know that we are different.  Who would know that the words we speak give life, and who would know that we are different and separated to the Lord?  What does the bible say about dress?  Job 40:10, "Adorn yourself with eminence and dignity; and clothe yourself with honor and majesty."  It doesn't sound like anyone's underwear is hanging out in this verse. How much dignity is there in exposing ones underwear?  How much dignity is there in a woman that will show everyone everything that only a husband should see?  Lets start with the first dress code ever. Genesis 3:7-11, No need to quote it all here, suffice it to say that when Adam and Eve sinned they knew they were naked and became embarrassed and ashamed.  They tried the fig leave thing and God made clothes even more unrevealing for them.  Adam and Eve said we shall cover ourselves with these skimpy little fig leaves and God said oh no you don't, as sinners you need to cover yourselves completely.  We'll use animals skins top to bottom.  God said you are sinners now and you need to cover all of yourself not just your loins.  Read it, that is one of the things it is saying.
       So where are we now that we've come to the 21st century?  We still have some very explicit directions from the Lord. Deuteronomy 22:5, "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."  Now you may say what makes up a man's clothing and what makes up a woman's?  We may be confused today, but yesterday we were not.  When I was a kid we were taught what was what.  Some things are obvious even today, but because we have lost our way some things are not. So I'll be real point blank about it. When I was young, a woman of any character did not wear t-shirts, shorts or pants.  Why? Because they reveal too much about a woman.  So any blouse that was to tight and to revealing was not worn.  When I was a boy women would not wear shorts much less hot pants.  Why do you think they are called hot pants?  The general rule was that if it aroused the passions of a man that should be reserved for marriage then our young ladies did not wear it.  In biblical times a woman who showed her leg and thigh was a harlot.  Why? Because it inflamed the passions of a man that were and are reserved for marriage.  It inflames men to sin. Any woman that provokes a man to sin is a harlot.  If what you wear invokes sin in a man's body or mind then you should not wear it.  And the same is true for men.
       But you say, "I need fashion it would make me look silly if I did not keep up with fashion." Lets see what Jesus Christ said about clothing and fashion. Matthew 6:25-34, "For this reason I say to you, do not be anxious for your life, as to what you shall eat, or what you shall drink; nor for your body, as to what you shall put on.  Is not life more than food, and the body than clothing? Look at the birds of the air, that they do not sow, neither do they reap, nor gather into barns, and yet your heavenly Father feeds them. Are you not worth much more than they?  And which of you being anxious can add a single cubit to his life span?  And why are you anxious about clothing?  Observe how the lilies of the field grow; they do not toil nor do they spin; yet I say to you that even Solomon in all his glory did not clothe himself like one of these.  But if God so arrays the grass of the field, which is alive today and tomorrow is thrown into the furnace, will He not much more do so for you, O men of little faith?  Do not be anxious then, saying, 'What shall we eat?'  Or 'What shall we drink?'  Or 'With what shall we clothe ourselves?'  For all these things the Gentiles (unsaved) eagerly seek; for your heavenly Father knows that you need all these things.  But seek first His kingdom and His righteousness; and all these things shall be added to you.  Therefore do not be anxious for tomorrow; for tomorrow will care for itself.  Each day has enough troubles of its own." In a nutshell, Christ has said don't worry about all the things that the unbelievers worry about.  Don't get caught with the unbelievers who seek after fashion and the "good life" that they will never have.
