While packing my clothes I used Huggable Hangers. I usually buy them on HSN but they also have them at Target and similar hangers at places like TJMaxx and Marshall's. I love these hangers because your clothes actually stay on them!
When I was done hanging my clothes, I used a large Ikea Bag. It's only $0.59 for one and is extremely durable! I then just neatly placed my clothes in the bag. It was extremely convenient because once I was all moved in, all I had to do was take the clothes out of the hanger and hang them up in my dorm closet.
