No matter how many clothes are in them, a closet simply does not have enough absorption material to keep the room resonances out. Because of that, the reverb, though extremely short, will be extra loud in the microphone (especially once the voice is compressed). So, think about this when you're recording vocals.
Why do people record audio in closets?
It lets the sound waves bounce around over its many little wooden squares, nooks and crannies, and in doing so, it helps the recording sound warm and natural. It gives it just enough reflection and bounce that it doesn't sound completely dead, because real life spaces do come with reflective surfaces.
