I love to wear sparkly things to work. The key is to add structured, classic accessories and tone down the jewelry. Sequins are such a great day to night item to wear and with a looser fitting tunic like this one, it's comfortable while maintaining a polished look.
I don't wear pants to work often, since I am constantly switching from flats to heels - but I love a pair of classic black pants. For work, you always want them to fit a little looser than you might wear for jeans or even a Friday night out. Check out more of my day to night sequin looks here, here and here.
