thistledown
- n pappus of a thistle consisting of silky featherlike hairs attached to the seed-like fruit of a thistle
- It does a fairly good job of trying to eat its cake and have it too: makes gay, simpering fun of itself while it strives after a light-as-thistledown charm.
- With her thistledown lightness and grace, pert, piquant Moira Shearer (dancing star of the movie Red Shoes) danced well and looked the part of Cinderella.
- Its romantic moods never quite blend Scotland with fairyland; the thistle is there, but not the thistledown.
