Trendy menswear brand Psycho Bunny, known for its colorful polo shirts and edgy logo, is heading to Westfield Montgomery mall. The company offers an upscale casual wardrobe — shirts, shorts, swim trunks and the like — all emblazoned with its signature image of a bunny skull and crossbones. Plans call for a fall opening on the mall’s lower level, next door to Aerie and Offline. Psycho Bunny will be the third men’s store to open at the mall this year, following the recent additions of Sayki and De Clichy.
