Outfits you buy often look older simply because they run colour in every wash. You need to stop the colour running from your brand new clothes at the very first wash. This helps to keep the colour as close to when you first bought it, for as long as possible. Add a teaspoon of common salt or a tablespoon of cooking vinegar to cold water. Soak your clothes in it for 15-30 minutes. If this is done at the very first wash, clothes will not lose colour as fast as they would otherwise during the subsequent washes
