how do you tell someone their clothing does not fit them?

<p>i know someone who’s really close to me…actually, they’re part of my family. But the thing is, every time I see that person, he’s always dressing as if he’s a teenager!! but he’s an adult!! I get so annoyed because its absolutely hideous. How can I tell him that the way he dresses does not fit his age, in a nice way? he has no taste…and he won’t listen to his friends’ comments…sigh.</p>
