The princess tiara is such a choice accoutrement. Girly, undeniably slightly ridiculous, but fun. It's clearly a "it's my night" thing to wear, so that bystanders seeing a rowdy girl group will know who the star of the night is. There was just such a case with this birthday party at Greenhouse. Accompanied by hands in the air, bottle service, and lots of hugging/i love you moments; this birthday girl seems to have brought in another year in bubbly, bejeweled style.
