I swear, there's a phrase (a simile) I hear a lot that describes when someone just appears different from everyone else in a given crowd or location.
For example, (and I'm trying to be as sensitive as I can), something like a tall person in a midget convention or something. Or a blue bowl in a cupboard filled with red dinnerware. A person (or thing) that just utterly and completely doesn't fit in with everyone (or everything) else there.
I've been trying to look up this phrase for the past half an hour at least, and my Google searches are just not returning anything useful.
Are there any phrases or similes that come to mind?
