Next month, Pippa Middleton will be walking down the aisle to tie the knot with fiancé James Matthews. But before she slips on her gown, she's preparing by working out at the KX Gym in Chelsea, London. On Wednesday, she was spotted leaving an hour-and-fifteen minute Pilates class. And as usual, she looked amazing, wearing a hooded top ($136; by Swedish brand Peak Performance and Nike shorts (shop similar here).

VIDEO: Pippa Middleton's Best Style Moments

We were really excited to see that she styled her workout gear with an affordable pair of sneakers. The New Balance Fresh Foam Zante V3 Breathe Pack Running Shoe ($100; is perfect for just about any workout. And while Middleton chose the white and gray style, they are sold in a ton of other colors—like neon green and cool rose gold. Overall, this look is definitely inspiring us to hit the gym.
