wear ＋衣服中间需要加a吗

用的

例如：

1. Do you wear glasses?
   你有戴眼镜么？
   
2. I wear a headband.
   我绑头布。
   
3. I wear contact lenses.
   我戴隐型眼镜。
   
4. I wear the clothing.

要加.例如:Do you know the man wearing a black coat?

有时加定冠词或物主代词.例如:Why do you always wear this T-shirt?

I forgot to wear my favorite leather-jacket.

满意否?
