How to say "sleek" in Japanese

• さらり
  adverb (with と)Covers sleek in the sense of a light, effortless smoothness of texture. As a mimetic word, it fits when you want to convey smoothness that feels airy rather than heavy or sticky.
• すべすべ
  no-adjective, na-adjective, adverb (with と), suru verbCovers sleek as a tactile quality: something pleasantly smooth to the touch, like skin or stone. Its sleekness is velvety and silky — one you feel with the fingers, not one you see.
  このスカーフは手触てざわりが柔やわらかくてすべすべしている。↗

  This scarf feels soft and smooth.
• 艶やかつややか
  na-adjectiveCovers the visual sense of sleek: a glossy, lustrous shine, as of hair. Use it when sleek means catching the light attractively rather than describing how a surface feels.
  最後さいごに出でて行いったのは背せの高たかい男おとこで、顔かおは青白あおじろく、つややかな黒くろい髪かみをしていた。↗

  The last to leave was a tall man, with a pale face and smooth, black hair.
• スレーキ
  nounA katakana term for a fabric, not for the quality of being sleek. Unless you are literally naming that textile, this is seldom the word you want when translating sleek.
• ぬめっと
  adverbCovers a wet, slippery kind of sleekness: the glistening sheen of a moist, slick surface. For sleek in a clean, glossy sense, this is seldom the word you want.

All five are less common choices, so pick by sense: 「すべすべ」 for tactile smoothness, 「艶やか」 for glossy luster, 「さらり」 for a light smooth texture, 「ぬめっと」 for a wet slippery sheen, and 「スレーキ」 only for the fabric.
