There is a lot of material online that suggests dressing conservatively in Dubai. But Dubai is the fashion capital of the world and dressing dowdily to 'cover up' is not an option.
I suggest packing loose comfortable trousers and tops in luxurious fabrics. Opt for rich colours and bohemian silhouettes. This way you can look stylish without showing too much skin. Combine them with flat sandals because you will be walking a lot in Dubai.
Keep your hair out of the way with a fuss-free top-knot and accessorise with gold accents.
