Mix, match or go all-in
Every item can be bought on its own, or grab the value four-piece set that includes the tee, wig, tutu and socks together:
-
Thing 1 or Thing 2 T-shirt — bright red cotton-feel tee with the iconic circular "Thing" print (available in M and XL).
-
Blue curly afro wig — the unmistakable fuzzy blue hair, with a stretchy elastic base to fit most adults and teens.
-
Blue tutu skirt — layered tulle for that playful, bouncy shape.
-
Red & white striped socks — over-the-knee stripes to finish the look (about 50 cm high).
