Pippa Middelton is getting married to her longtime boyfriend, financier James Matthews on Saturday, the 20th of May.

After making headlines the world over as bridesmaid at sis Kate Middleton's 2011 royal nuptials for dat ass, we're now looking forward to her next iconic style moment.

But first:

Meet her fiance...

Meet her ring (it's basically its own constellation)...

According to Town and Country Mag the couple's wedding will be celebrated at Carole and Michael Middleton’s Georgian property in the village of Bucklebury.

This is what we know: Pippa is a traditional style girl. And according to NYMAG she told guests to bring two outfits for the day - one for the ceremony, and one for the reception. We can only assume that means she will also be donning not one, but two outfits.

While she definitely won't wear a sack of silk, she could totes still pull it off, I say!

It would be so ideal for a country wedding - just add floral crowns, The Lumineers and a picnic-style reception.

But this is what I predict for outfit numero uno:

I'd love to see her in cascading lace and not necessarily in virginal white.

Elie Saab

But I'm certain she will go for something from Ralph & Russo. Something classic, fitted and traditional with minimal pizazz. But in a fabulous way.

And this has to, as in HAS TO be her second outfit!

Please Pippa, please wear this cowboy-inspired Dior - you don't even have to leave your hat on.

OR if she's going for a Gatsby-style reception, maybe this Chanel?

What do you think? How would you dress the Duchess of Cambridge's sister?
