Just in time for summer's impending heat, the lob--or long bob--has been trending among stars like Jessica Alba, Jennifer Lawrence, Kaley Cuoco, and more, but little did we know that a Middleton would be the next to take on the trend. A longtime stickler to her traditional silky brunette strands, Pippa Middleton debuted a slightly shorter cut at the Waitrose Summer Party last night in London. Like her older sister, the younger Middleton rarely changes up her trademark look, so it's nice to see a style switch-up (however slight) amongst the notoriously conservative royals. This leads the rest of us to wonder, will Duchess Kate be following suit?
