Trending: cardigans with elbow patches.

Had a discussion at work about elbow patches on cardigans. I've noticed them in shops when I've been looking for cardigans. People are wearing them. They seem to be taking off. I'm not going there personally because I think the cardigan is a serious item of clothing, which rises above such fickle trends. It doesn't need to look in season or fake vintage. I know there are connotations of "grandpa fashion" or "hipster" but to me a cardigan is a jumper that opens down the front, which is excellent in itself. Functional and smart.
