Throwaway clothing (an idea that seems absurd to me) is so widely used that it is a major source of greenhouse gases and plastic waste.

When cotton is used, the growing of the cotton releases fertilizer runoff and competes with food production.

We can hope that people will turn towards rejecting throwaway clothing (and any non-durable clothing), but that involves going against social pressure. Turning the pressure around would have more effect. Perhaps a 300% tax on clothing that appears designed to last less than six months, decreasing to zero for clothing that would last three years. Alternatively, require the store or the "brand" to buy the clothing back within three years, and put up a deposit for doing this.

Another alternative: if you want a design on your body just once, paint it on.
