Is it ok for Pagans/Wiccans/Witches to wear fashionable clothing such as D&G, Giorgio Armani, and the like?

Paganism, Wiccanism, Magick, any nature religions have absolutely nothing to do with what you wear on the outside in my opinion. It is about how you work with spirit and connect with nature through ritual, service and meditation. It is about love and self respect. Hey, if wearing some nice threads makes you feel confident and happy, your practice is going to be better for it. Plus its good for the image of the paganism because if people see that pagans aren't all hippies and/or goths they will give it more respect.
