este traje/lana i am not sure what to do

Thank you for using the Jiskha Homwework Help Forum again. Yes, there are two "de's" because here is what it says: The dress OF stripes (the striped dress) OF cotton (cotton) OR the striped cotton dress.

The second question was just answered above.

Yes, you are correct! In the phrase "el vestido de rayas de algodón," there are indeed two instances of the preposition "de." Let me explain how to identify and understand their usage:

1. "De" as a possessive: The first "de" in the phrase is used to indicate possession or the material of the dress. In this case, "de rayas" means "striped" (literally "of stripes"). So, the dress is "el vestido de rayas" ("the striped dress").

2. "De" as a material description: The second "de" is also used to describe the material of the dress. In this case, "de algodón" means "made of cotton." So, the dress is "el vestido de rayas de algodón" ("the striped cotton dress").

By using both "de" constructions, the phrase provides additional details about the dress, emphasizing its material and pattern.
