How to say "fiancee" in Japanese

• フィアンセCommon
  nounThe loanword for the person one is engaged to, used of either a man or a woman. It carries a slightly foreign, stylish flavor and is typical of wedding talk and celebrity news.
  白しろい洋服ようふくを着きている子こが私のフィアンセだ。↗

  The girl who is dressed in white is my fiancée.
• 婚約者こんやくしゃCommon
  nounThe kanji term, literally 'engagement person': the neutral word for the person one is engaged to, of either sex. When in doubt between the two, this is the word to reach for.
  ケイトは婚約者こんやくしゃからもらった大おおきなダイヤモンドの指輪ゆびわをいつもみせびらかしている。↗

  Kate always shows off the big diamond ring she got from her fiance.

Both words denote the person one is engaged to and overlap almost completely: 「フィアンセ」 is the katakana loanword with a foreign flavor, while 婚約者 is the plain kanji term that suits nearly any context.
