My mum sometimes wears my clothes, but its just my hoodies if she wants to nip out to the shops and she wants something warm to wear. However, if its cold out and i'm with my dad, he lets me borrow his jacket (actually, he makes me wear his jacket sometimes). But its usually not an issue because, 1.) I'm a girl therefore my brother or my dad don't want to borrow my clothes (i'd be worried if they did), and 2.) me and my mum are different sizes, and my clothes don't appeal to her (unless its my university hoodie as I have stated above)
