How to say "slim" in Japanese

Choosing the right word
  • 痩せるやせるJLPT N4approx.Common
    ichidan verb, intransitive verbA verb meaning to become thin, lose weight, or slim down. It describes a change of state, as in a person slimming through dieting, and is the natural choice when 'slim' is a verb about weight loss.
    若わかい頃ころは痩やせてたんだよ。↗
    I used to be thin when I was young.
  • スリムCommon
    na-adjectiveA loanword adjective describing someone or something as slim, with a positive, stylish nuance. Use it for a slim figure or for slim, streamlined objects such as bags or designs.
    スリムという名なの男おとこが事故じこで死しんだ。↗
    A man named Slim was killed in that accident.
  • 繊細せんさいCommon
    na-adjective, nounIts glosses center on dainty, delicate, and fine, as in delicate fingers or fine features. It covers 'slim' only in that thin, refined sense, so it is seldom the word you want for a slim body or figure.
  • スマートJLPT N2approx.Common
    na-adjectiveA loanword meaning slim or slender, typically with the impression of a neat, smartly proportioned figure. It is a good choice when 'slim' suggests an attractively trim build rather than plain thinness.
    あんなドレスが着きられたらいいんだけど。もっとスマートにならなくちゃ。↗
    I'd love to be able to wear a dress like that. But I'll have to lose some weight first.

For 'slim' as losing weight use 「痩せる」; for describing a slim figure choose 「スリム」 or 「スマート」; 繊細 means delicate or fine rather than slim, so it rarely expresses body shape.
