<P> She has some difficulty expressing her feminine side , because she views traditional feminine traits as restraining and outdated . She dislikes skirts , makeup , and dresses , and insists on wearing jeans at all times , but she will dress nice for special occasions and tried `` being pretty '' for her prom and for a trip to a nightclub , where the bouncer judged her `` foxy '' . As another exception , after her wedding with Eric was called off , she decides to change her looks and dyes her hair blonde . Jackie Burkhart repeatedly calls Donna a `` lumberjack '' and a `` giant '' , due to her penchant for plaid shirts and her tall stature . She even described Donna by saying `` She 's nice and all , but she kinda dresses like a trucker '' . She also teases Donna for her gargantuan feet , calling her `` bigfoot '' and saying things like Donna 's shoes are big enough for Jackie to fit her own shoes into . </P>
