Leggings are devices used for legs.

I’d write an ode to leggings the most comforting of “pants”,
But a picture’s worth a thousand words, a vis’ual dalliance.
But then I’d have to take a photo, one or two or three,
and put them up online to let the whole wide world in to see.
Instead of celebrating thus and hashtagging for attention,
I sing an ode to the lyrca blends that make up my collection.
