Here is a list of accessories you can wear to work.
Earrings – round screw earrings or little once are the best. Avoid long earrings or any large pair of earrings.
The watch – wear a simple black or brown leather watch; bracelet watch is also a good choice to compliment your work outfit.
The shoe – office shoes must be whole, do not wear sandals. Ballet flats and heeled shoes are the best choice.
Brooch – if you are wearing a small earring and you are not a fan of necklace, you can wear a small brooch to compliment your white or black shirt.
Scarf - it is a simple but perfect accessory for a workplace. With this, you do not need a necklace or brooch.
