According to my copy of The Know-It-All's Guide to the World, knitted pants are a knitted no-no.
I don't care that they have cool cables running down the sides of the legs.
I don't care that they match your knitted sweater perfectly.
I don't care that you're a grown woman who wears her hair in pigtails* and carries around a balloon for no apparent reason.
Just don't do it.
. . .Well, unless you really want to, of course. No-one can stop you but yourself. But don't come crying to me when people stare. (The world can be so cruel. . .)
*It has come to my attention that in some regions of the English-speaking world, "pigtails" refers to two braids of hair (Pippi Longstocking-style hairdo). Apparently they call this style "bunches" or "angel wings". Huh. You learn somethin' new every day. (Whether you like it or not.)
