Hoity Toity is a fashion designer and critic from Canterlot. He appears to be based on Karl Lagerfeld (note the white hair and fan cutie mark). He always wears sunglasses, even indoors.
He makes his first appearance in Suited For Success, when Spike invites him to Ponyville to judge Rarity’s fashion show. He appears sporadically throughout the series, usually in episodes that revolve around Rarity and her fashion career.
