"She touches my clothes."
Translation:Ela toca minhas roupas.
From different exercises and discussions, I have gathered that roupas (pl.) is a bunch of clothes in general, like what's hanging in your closet, and roupa (s.) is one set of clothes that you would wear. That's why we need roupa limpa, clean clothes to wear, but she is touching minhas roupas na minha mala.
