To produce a kilo of cotton (roughly equivalent to a t-shirt and a pair of jeans) takes 20,000L of water. It’s just fundamentally an extremely thirsty crop.
Not to mention that cotton is notorious for depleting soil nutrients, so it is often grown with very large amounts of fertilizer, which also polluted waterways and their outlets into the oceans.
