Pippa Middleton graced the Cheltenham Races in London, looking stylish as ever. But wait, did she steal the ensemble from her sister's closet? Check the slideshow to find out!

The royal sister rocked a chic winter outfit composed of a mustard yellow Katherine Hooker coat and a fur Cossack hat, which she matched with a pair of oversized shades and a Kate Spade clutch. The outfit was strikingly similar to the one the pregnant duchess wore to the same event back in 2006, where she donned a beige coat by the same designer and an identical hat.

Both Middleton sisters are known to be big Katherine Hooker fans, with the two even sharing the same coat from the British designer.

Days before the event, Hooker announced that the younger sister of the Duchess of Cambridge would be attending the races in one of her bespoke £815 coats.

She also tweeted, "The sun is shining at Cheltenham and how GREAT does Pippa Middleton look in her Katherine Hooker Tori coat?"

So does this mean Pippa wore it better than Kate?

Meanwhile, not only her look stole the crowd's attention that day. Pippa also caused quite a stir when she showed up with wealthy banker Tom Kingston, with the two laughing and grinning as they watched the race from a private box.

But let's not get too excited here. Apparently, Kingston has frequently attended sporting events with her in the past. In fact, they were first spotted together in November 2011 at the ATP tennis finals, proving that the 29-year-old party planner is just good friends with the eligible banker. Besides, Pippa is all loved-up with her current beau, Nico Jackson, with the couple just returning from a ski holiday in St. Moritz, Switzerland.
