Winter is coming,we need [to wear] more clothes to get warm.为什么不用 to put on?

-put on 穿；戴；涂；抹 是瞬间动作
例：
She put on her coat and went out...她穿上大衣出去了。
Maximo put on a pair of glasses...马克西莫戴上了一副眼镜。
I haven't even put any lipstick on.我甚至还没抹口红。
-wear 穿着；戴着；面露；留着 表示一种状态
He was wearing a brown uniform...他当时穿着褐色的制服。
I sometimes wear contact lenses...我有时戴隐形眼镜。
She can't make her mind up what to wear.她拿不定主意穿什么。

这里不需要强调动作啊,
只是说 需要穿更多的衣服来保暖.wear sth.戴/穿着某物
不懂再追问吧!
