for (int i = 0; i < shirts[0].length; i++) {
        for (int j = 0; j < shirts[1].length; j++) {
            for (int k = 0; k < shirts[2].length; k++) {
if (i != 0)
                    System.out.print(shirts[0][0] + " " + shirts[0][i]
                            + " ");
                if (j != 0)
                    System.out.print(shirts[1][0] + " " + shirts[1][j]
                            + " ");
                if (k != 0)
                    System.out.print(shirts[2][0] + " " + shirts[2][k]
                            + " ");
                System.out.println();
            }
