Clothes:

Jeans: 4 to 6 pairs
Shorts: 6-8. Get those ones, which are, long and go a 2-3 inches beyond knees.
T-shirts: 6-8
Cotton shirts: 4-5(no multicolored patterns, they are not in vogue in US). Cotton clothes are good in warmer places.
Night clothes: 2-3 pairs
Formal suit & Ties - 1-2 pairs. You rarely need them...once in a year or so on occasions like Convocation ceremony and interviews.
Undergarments...a lot of them...10-15 pairs we stress upon this because you may go to the laundry once in two weeks!!
Socks...4-5 pairs you can bring even more because you would be wearing shoes most of the time. Do not take nylon socks. Cotton ones are better.
Sweaters. a couple - full sleeved advisable
Get a muffler and monkey cap and woolen gloves and windcheater.
Leather jacket...1 they are rather poor protection in the north. But you may consider getting one woolen Jacket.
Handkerchiefs-1 dozen
2-3 belts one formal leather belt and others as you please. But you might want to know that one rarely tucks in the casual dresses.
Kurta-payjamas-These would be good during Cultural meets etc. If you have fancy for one, don't forget extra naadi then.
2 Turkish towels and two napkins.
2 thin single bed sheets.
One air pillow
