Tips

Layering is your friend; a nude or matching camisole underneath thin fabrics ensures complete opacity.
Choose breathable fabrics like cotton or bamboo blends if you are going to be indoors or moving around a lot.
Focus on iconic props (like a book, a wand, or a magnifying glass) to make a simple, modest outfit instantly recognizable.
Ensure your skirts or pants are hemmed to a safe length so you do not trip while walking or climbing stairs.
