Disappointed with the color of the clothes

I am very disappointed with old khaki, I bought an olive short for my husband end of November last week it was my first time washing it, the color has worn out already it looks like it has been worn for years. I used a bar soup and I used my hands washing it. If it was for me I would have took the khaki one because the colors is bad its not even a month but im not happy with it 😢😢😢😢to think I paid R600 for something that might never be worn again
