   Modesty is befitting to a young girl.

• 1.
  Synonym適切てきせつNeutralThe everyday word for 'appropriate': it judges whether something is exactly right, as in 「適切な処置」, without the nuance of looking becoming on a person.
• 2.
  SynonymふさわしいNeutralClosest to the headword: says something matches a person's status or the occasion, as in 「ふさわしい服装」. The everyday choice for 'befitting'.
• 3.
  Synonym似合わしいにあわしいNeutralSays someone or something harmonizes with a person's traits or position; in meaning it matches the headword almost exactly.
• 4.
  Synonym相応そうおうNeutralThe noun-based counterpart: befitting one's age or standing, as in 「年相応」. Focuses on matching status or ability.
• 5.
  SynonymしかるべきWrittenWritten prose. Points to what is due or called for — the response that naturally should follow, as in 「然るべき処置」.
• 6.
  SynonymもってこいCasualColloquial: something could hardly be more ideal for a purpose, as in 「散歩に持ってこいの日」. Much more casual than the headword.
• 7.
  Synonym適したてきしたNeutralSays something suits a purpose or use, as in 「〜に適した場所」; centers on fitness for a function.
• 8.
  Synonym好適こうてきWrittenWritten prose. Says conditions or surroundings are exactly right; mostly used of environments and conditions.
• 9.
  SynonymうってつけCasualColloquial: nothing could be more suitable, as in 「打ってつけの人材」. Casual speech for an ideal, perfect fit.
• 10.
  Related適当てきとうNeutralCovers both 'appropriate' and 'careless': can praise something as fitting, but often suggests a perfunctory, half-hearted attitude.
• 11.
  RelatedよろしいFormalFormal. A stately way of saying 「よい」; leans toward permission and approval, 'that will be fine', rather than judging fitness.
• 12.
  Related手ごろてごろCasualColloquial. Size, price or level being just right and handy, as in 「手頃な値段」 — convenience and moderation, not becomingness.
• 13.
  Related合うあうNeutralAn everyday verb: things or people match, fit or agree. Describes the fitting itself rather than passing judgment on what is proper.
• 14.
  Related適任てきにんNeutralSays a person is qualified for a particular post or task — competence for a role, not general becomingness.
• 15.
  Relatedそれ相応それそうおうNeutralSays something is proportionate to the situation at hand, as in 「それ相応の報酬」 — matching the circumstances themselves.
• 16.
  Related分相応ぶんそうおうNeutralLimited to matching one's own status or ability — living or acting within one's means. Much narrower than the headword.
• 17.
  Antonym似つかわしくないNeutralThe negative the headword often takes: not becoming, looks wrong on that person or occasion — the direct opposite of the matching sense.

Use 「似つかわしい」 when someone or something looks right for a person or occasion — often as 「似つかわしくない」. For everyday 'befitting' pick 「ふさわしい」; for 'appropriate' in the sense of the right move, 「適切」; for a casual 'just right', 「打ってつけ」. The rest are narrower: 「然るべき」 and 「好適」 are written, 「持って来い」 and 「手ごろ」 colloquial, 「適任」 is for people fit for a role, and 「分相応」/「相応」 tie things to one's station.
