Tilly's opened its first store in 1982 in southern California, so it's only fitting that one of its larger stores would be in Santee's Trolley Square. Come in for a big selection of clothing for surfing, skating and the southern California lifestyle from brands such as Roxy, LRG and RVCA. You'll find everything from clothing to sunglasses at Tilly's, and it's all very competitively priced.
