Kendall Jenner isn't the only star sibling looking to make a splash in the modeling world!

Lindsay Lohan's younger sister Ali stars in a racy new ad campaign for 6126's spring/summer 2011 collection, where the 16-year-old dons a cleavage-baring coral dress and a skimpy lace number.

Inspired by Marilyn Monroe, the line "salutes modern women who understand that confidence can be bewitching and classic sophistication is always in vogue."
