She’s been having a ball checking out all that there is to offer at London Fashion Week. And last night, Mischa Barton even took some time to help out a charity.

The “Oh in Ohio” hottie was spotted attending the Fashion For Relief fundraiser, held at the BFC tent at the Natural History Museum in downtown London.

Always one to take chances with her wardrobe, Miss Barton sported a sleeveless belted red and gold patterned dress with silver bangle bracelets and leather heels.

Earlier in the day, Mischa was spotted hamming it up at the Samsung Imagination Ico Series presentation of “The Red Thread: The Inspiration and Passion of Valentino Garavani” as part of London Fashion Week.
