Technically you are correct, it is a valid translation, but I believe 'usar ropa' would be used in a sentence like this: "Yo uso ropa interior", which would mean 'In general I wear underwear." or another example- "Yo uso ropa Abercrombie" talking about the fact you wear Abercrombie clothes. But I don't believe that you would say "Voy a usar esto." to mean "I wear this." because you are talking about a specific garment. You would say 'Voy a ponerme esto." Unless maybe you decided to like, wear one shirt and one shirt only everday day after day, or at least very often, then "Voy a usar esto." would be appropriate. "Voy a usar esto" isn't really wrong. But it's not common usage.
no problem. I love helping out in discussions. I didn't really know the answer either but I learned it by typing in various phrases to the google.es search and came up with that answer so your question was very helpful to me too sallyann. I feel like I learn way more by participating in sentence discussions than doing immersion. Of course I only really tried the immersion once and it was this wikipedia article about pineapples and it had a ton of words that I didn't even know what they meant in English so I didn't think it was really worth my time to learn them in Spanish.
