The could-have-been-royal was spotted arriving at Glastonbury with friends dressed in white dungarees, worker boots, an adidas Originals zip up and a navy beanie hat. Teaming her getup with a heavy gold chain and pigtail braids the former dancer looked like a hip hop Pippi Longstockings.
If Kanye West wrote children's books, Cressie would probably be the main character. Now there's a sentence you never thought you'd read.
After all that it's no wonder she needed a stiff drink... Well a Strongbow at least.
According to the MailOnline the 25-year-old rejected claims that she would be "glamping", or staying in luxury camping facilities, saying she was looking forward to camping with friends who had already arrived.
"It's my third Glastonbury," she told journalists. "I'm staying with some friends who have pitched up a tent."
However, from the looks of the weather report that could be a decision she lives to regret.
It is thought that the 25-year-old socialite is following what has been coined as the "Kate Middleton strategy", firstly by stepping out looking incredible in a backless jumpsuit and then partying with Brit heart-throb Benedict Cumberbatch.
According to the London rumour mill, Cressie joined the Sherlock star at celebrity hotspot Chiltern Firehouse while out partying with Princess Eugenie in the hope she'd make her prince jealous.
"Cressida has taken a leaf out of Kate's book. She looked absolutely stunning in her outfit [the other] week and there's one man who she will have wanted to see those pictures - Harry," a source told The Mirror.
"They got on really well. Could they find love again, like Kate did? It's possible."
To be fair, who wouldn't want to keep hold of this eligible bachelor?
