Those are Our Fashion Experts - They are called 'Fashion Twins' & they can give fashion advice to any Girl in Troll Village! :)   

( So I was honored that when they 'needed some male Troll's opinion' before one of our Twitter Parties - they showed their new party dresses to Me & asked me 'if they look good enough in them' - because They Knew that I'm Always Honest & Say What I Think! 😊 - They Both Looked Beautiful, & were 'the Best Dressed Troll Girls at The Whole Party' - as usual !  ^_~ 👍 )
