Consider an additional layer. Once you’ve chosen a third piece, you may or may not want to add another layer to your outfit. If it’s going to be a chilly day, create another layer by tossing a cool hoodie over your casual jeans, t-shirt and flannel button down to complete the look.[8] If you’re wearing a tank top underneath a sheer, long-sleeved blouse, consider adding a sleek, structured blazer on top as an additional layer. This will give the outfit another dimension and a more polished final look.
