As a student at Cal, I used to shop at Bear Basics frequently. On their main floor, they have tons of Cal merchandise, including clothing, accessories, knick knacks, hats, and more. Upstairs is a nice selection of trendy clothes for women. I used to find some really cool stuff for really good prices up there. Sometimes they even carried some vintage pieces. Their basement is called the "T-Shirt Orgy" and is full of t-shirts that run the gamut from fun, quirky, sarcastic, band shirts, TV references, etc. If you like screened t-shirts with funny or controversial things on them, you're likely to find something to suit your style down there.
