It was difficult to get a direct answer as I perused Google. I found a handful of different figures that give sort of a ballpark idea. According to a recent survey conducted of women's shopping habits, "It appears most women, on average, will spend somewhere between $150 and $400 on clothing on a monthly basis, which equates to approximately $1,800 to $4,800 per year." Credit Donkey states, "The average adult aged 25-34 spends $161 per month on clothing." ($1,932 per year).
