I have a question regarding hijab. Am I allowed to wear a dress with patterns, such as flowers or dots? Or is it considered adornment? My dress is modest, loose, long, covering and not see-through.

As long as your dress fulfills the requirements of the shariah law of modesty and hijab that includes loose clothing, long sleeves, covering all the body parts including the head and chest, it is fine. As long as the dress isnt attractive and provocative
