。
She pulled the sweater on over her head.
Literal
She [topic-は] sweater [object-を] head [from-から] putting-on [then-て] wore.
Japanese splits the verb 'wear' across multiple lexical items by what's being worn — 着る for upper-body clothing, 履く for lower-body and footwear, かぶる for things put on the head, する for accessories like ties and gloves, かける for glasses. Here the sentence stacks two of those: 頭からかぶる ('to put over the head') describes the manner of donning, and 着た ('wore / put on') wraps it up as the completed act. から ('from') marks the starting point of the motion — the head is where the sweater begins its journey. The te-form かぶって links the two verbs in sequence.
