Sibling Pink. Last weekend, Sibling presented their Fall/Winter 2015 collection during London Collections: Men. Titled Judy Is A Punk (a song by American punk-rock band Ramones), collegiate scarves, hats and rugby socks display a punk and rebellious attitude. Spotted, checkerboard, argyle and Fair Isle patterns were employed along the crew neck jumpers and cardigans. Pink was the predominant color but no a common pink, but the Pink Sibling as it became rapidly known. Khaki was also use on some on the looks in a wrinkled way as a reference to the paper that cover books.
