QUESTION

I am in my late 20's and 1.54m in height. Due to my health issues I struggle with my weight and am currently 94kg with a round tummy. It is difficult to find clothes that suit my shape/hide my tummy and clothes in my size are usually too long and make me look frumpy and much older. I am afraid of having tops and dresses altered for fear that they will be ruined. Are there any stores which cater for shorter plus size women? What styles would best suit me?
