Lindsay Lohan and her little sis Ali stepped out to celebrate the launch of the elder Lohan's new self tanner last night. Lindsay, wearing an ivory dress (tunic? long shirt?) and platform Alexander Wang sandals, made an appearance at the Sephora in Santa Monica on behalf of her tanning mist, "Sevin Nyne".

Lindsay is looking a little orange in the face here, which makes me seriously question Sevin Nyne (why can't it just be Seven Nine?). If the face of the product shows up to the launch looking like she had a self tanning accident right before she arrived…yikes.
