After creating a party-useful tee to celebrate Hello Kitty’s 35th Anniversary, MACKDADDY brings its playful humor to its collaboration with G-Shock. The Japanese label partners up with Casio’s toughest and dresses the classic shock resistant DW-5500 in a preppy happy pink plus green color combo. Featuring MACKDADDY’s type logo on the watch strap and graphic logo on the watch face, the happy number will be available at on Nov 20.
