To wear with my kilts I have favored long socks of various types and textures. They range from thin silk socks to thick wool socks, also cotton and acrylic. some are smooth others have textured stripes and others have cable or rope texture. Colors range from black and navy blue to primary colors like red and yellow, also dark red and dark green and grey, even brown, and beige. Of course the traditional off white cable knit does show up but really only in cotton.
