Princess Eugenie Wows In The Perfect Print Dress For Tracey Emin's Birthday Bash

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.

Eugenie wore a standout skater dress (check the pen and floral motif) complete with black, white and blue colourways, an embellished black clutch and classic black ankle strap sandals. Pretty killer and there wasn't a fascinator or nude heel in sight.

The 24-year-old royal was joined by her longterm boyfriend Jack Brooksbank and the couple could not have looked more loved up during last night's celebrations.

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.

The princess posed for photos with Emin who wore a LBD, navy blazer, black heels and matching necklace and earrings.

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.
