However, in contrast to the 1960s-style mod-influenced Trojan skinheads, white power skinheads have typically worn higher boots, T-shirts, flight jackets (especially in black), and army trousers or jeans instead of Sta-Prest trousers or suits, although some white power or moderately right-wing/nationalist skinheads may dress quasi-traditional with Fred Perry or button down shirts and Harrington or denim jackets. Often, white power skinheads wear badges, chains or rings featuring Nazi or white power emblems.[24][25] In some cases, white power skinheads fit their boots with white (or alternatively, red) laces to signify their affilations. These laces are usually done in a "ladder" style (laces are done horizontally instead of crossed), and in some gangs, these laces must be earned through acts of racist violence.
