The stars came out in costume this weekend for the 16th annual Children Affected by Aids Foundation’s Dream Halloween event. The goal of the night, which also includes fundraising, is to create an experience that exemplifies what every child would dream of when celebrating Halloween. Celebs in attendance included Jamie Lee Curtis as a flower child (who also arrived in her hydrogen-powered Honda Clarity), Daryl Hannah as a cat, Hilary Shephard as Dorothy, and Noah Cyrus and Emily Grace Reaves as, well, I’m not sure.
