Slip your sweater over a loose white shirt, with puffed sleeves or not. Weather permitting, a plain sweater can be worn with a maxi printed long sleeves dress. It can also be worn over a simple long white shirt over jeans and sneakers.
To dress well for school, your uniform must be well-fitting, but comfortable clothes with colours that complement each other. Whether you're a boy or a girl, it's tough to beat a pair of great-fitting clothes. They can be worn just about every day and they go well with most shirts and tops.
