Penelope Cruz and lil sis Monica Cruz celebrate their clothing collection for Spain-based fashion chain Mango on Monday at Atzaro Hotel in Ibiza, Spain. The identical-twin fantasy actress/designer sisters designed a collection together based on vintage pieces from their own wardrobes with a mix of red-carpet-inspired evening wear, jeans, knits and daywear. Penelope has said, This is something weve wanted to do for a long time. We just had to find the right people to do it with. Weve always loved clothes we used to hide in the bathroom with fashion magazines and say, I want that one. Penelope, 33, and Monica, 30, plan to launch their collection on Sept. 16.
