Princess Eugenie pulled out all the sartorial stops to celebrate Tracey Emin's birthday at Mark's Club in London on Thursday night.
Just when we thought Eugenie was all about low-key dressing (she played it safe in a pastel blue shift dress for the Serpentine Gallery summer party on Tuesday) she opts for a statement print.
They may be doing the long-distance thing while Eugenie is living and working in the US (she's just back in Blighty to visit friends and family and attend glamorous parties) but clearly they're making it work.
While Emin was celebrating her birthday with a close circle of celeb friends (Vivienne Westwood and Bob Geldof to name a few) last night, we're guessing she was also letting her hair down after her iconic installation, 'My Bed', sold for £2.54 million at Christie's auction on Tuesday. Now that's how to kickstart a birthday.
Now that Eugenie is well practiced in the auctioning game - she works for online auction house Paddle8 in America - rubbing shoulders with renowned artists is a regular thing.
