I don't know what's behind it, but headbands with tiny hats are popping up all over. The top hat hair accessory trend has been around for quite some time, but the look has branched out to include all sorts of hats, like Urban Outfitters' bowler hat headband ($28), a teeny-tiny ribboned variation of the top hat headband ($18), and a cocktail hat headband ($28). There are plenty more, as well, with Forever 21 offering up some rather sparkly designs. What do you think of this trend? Do you tip your hat to it?
