She found me a lovely tie.
Literal
She [topic-は] me [to-に] lovely necktie [object-を] found [for me-てくれた].
ネクタイ is the standard Japanese term for 'necktie' — borrowed directly from English. Like many men's-fashion loanwords (シャツ 'shirt,' スーツ 'suit,' ベルト 'belt'), it dates from the Meiji-era westernization of Japanese male professional dress. The verb 見つける is the transitive 'find, discover, spot'; in kana みつける it shows up in casual writing. The pattern noun + を + みつけてくれる ('find X for me') is one of the most common everyday gratitude expressions.
