An oversized t-shirt is a loose-fitting t-shirt that is designed to be bigger than your typical size. They can be one or two sizes larger, or even more, depending on the look you're going for. Oversized t-shirts are meant to have a baggy, relaxed silhouette, and they can be a comfortable and stylish option for both men and women.There are a few different ways to style oversized t-shirts. You can wear them on their own with a pair of skinny jeans or leggings, or you can layer them under a jacket or cardigan. You can also tuck them into a skirt or pair them with shorts. Oversized t-shirts can be dressed up or down, so they're a versatile piece that can be worn for a variety of occasions.
