There is a jargon used for clothes that look older than they really are – Distressed clothes. The crisp ‘just-bought’ look is tossed for a weathered ragged look – as if those clothing has been used for a long time.
With some easy ways you can alter the feel and look of the fabric to seem like it has aged naturally. The main things that distinguish a new fabric or clothing are its colour, texture, shine, presence of stains, signs of wear and tear including chips, tears and fraying. There are more than one ways to go about bringing about these signs and distressing fabric.
Multiple washing and drying
This is of course easy – wash the clothing repeatedly with strong detergent to fade its color. You can scrunch it and then let it dry in the same way for wrinkles. If that is not enough, hang the clothing in the direct sunlight (for a long long time) to fully fade and make the clothing look old.
Rubbing with things
You can rub the clothing with rough things – sandpaper is usually used. But anything that can agitate the fibers of the fabric is useful here. A foot file, rasp, seam ripper, vegetable grater, wire brush are all used to produce natural-looking distressed marks and even holes on the fabric.
Frayed edges are made by using a wire brush or the seam ripped. A haggard-looking hem is one of the most significant signs of old clothing.
You can rub on areas where there will be wear and tear – at the elbows, knees, collars, hems, backside, cuffs, under the armpits.
Bleaching involves using chemicals to fade the color of the clothing in selective places where there will be wear and tear – you can fade color outside creases, near the neck, top of the shoulder, etc. Or use a sprayer with bleach solution for a dotted effect.
A similar but lesser effective is using a solution of Hydrogen Peroxide on the clothing and then letting it stand in the sun.
You can dip the fabric in a very (very) diluted paints/dye solution in brown or black or grey or selectively apply color on areas where there are stains like necklines, hemlines.
You can make brownish streaks and dots to look like grass stains, dark brown color for dirt, light yellow ochre for deep sweat stain, and pale grey color for mildew spots. Test on an inconspicuous spot to see if the color is what you want.
One caution is not to use too much paint as it can cause the fabric to feel stiff.
Stretch the fabric
You can stretch it naturally by hanging when wet, putting heavy things inside pockets.
Loosen the stitches of the top corners of pockets, tips of collars for a naturally aged look.
Use a very diluted solution of coffee or tea to dye the clothing to look browner and older.
Do not go overboard. Remember that you want the clothes to be still useable, after you have done the distressing.
