If you show up on I-Day with your ID, paperwork, phone, charger, and a few pairs of compression shorts (and sports bras), you’re literally set. Anything else is a bonus — or a burden. Don’t buy or bring anything for your room until near the end of plebe summer and you know what’s permitted.
This is N*ot College, so no trips with mom and dad to Target or Walmart for crates, caddies and candles before showing up. During parents weekend, there is a pilgrimage to Target for things — but again, only after learning what your company allows. Mine got a Brita pitcher and a steam iron. She now has a Nespresso coffee maker, but that came only after 2/7.
Above all, bring a good and humble attitude. That, more than anything else, will serve you well.
