Dorm closets are notoriously small. Take only the clothes you like to wear. (If you don't like it you won't wear it.) Casual wear will be appropriate for classes and most college activities. If you will be able to go home occasionally, pack for one season and switch out clothes for the next season when you go home. You can span any seasonal gap by layering clothes. Remember your rain gear. Bring a small sewing kit for sewing on buttons or making repairs. Check with your dorm about communal irons and ironing boards. If they are not available you will need an iron. Your bed or a sleeve board can take the place of a full sized ironing board.
