While both girls’ hoodies and girls’ sweatshirts are shirts with long sleeves, girls hoodies also have a front pocket around the midsection, sometimes are zippered, and have an attached hood. Both shirts can use the same materials and color patterns, but hoodies tend to be slightly more casual, while you can dress a sweatshirt up under the right circumstances. For example, she could dress in a hoodie on the way to soccer practice or even train in one if it’s cold out, and wear a sweatshirt with some nice pants for a backyard barbeque at Grandma's house.
