She had new clothes made for her.
Literal
She [topic-は] new clothes [object-を] make received-favor-of.
~てもらう is the third pillar of the giving/receiving verb system. While ~てくれる means 'someone does X for me (from their initiative),' ~てもらう means 'I receive the favor of someone doing X (often at my request).' Here, she arranged to have clothes made — the agency is hers, even though someone else did the making.
