I have a friend who hates the phrase "tiny little". I understand. "Very unique" makes me a bit nuts, as do people who use "blasť" when they mean "blah".
But when you're driving along with the windows wide open because L.A. is on the verge of one of its annual mid-winter bursts of spring, and you check the rear view mirror and there she is, Maisie the Teacup Lab®, stretched to her full height so she can stick her head out the window, there's no other way to say it.
Look at the freakishly small dog sticking her tiny little head out the window! Very unique!
