Whoville, the fictional town in the classic illustrated books "Horton Hears a Who!" and "How the Grinch Stole Christmas," is a creation of Dr. Seuss. It is expected that a Whoville costume would be playful, colourful and more than a little nutty. Still, there is no one right way to dress like a person of Whoville. As you construct your costume, study the books--or the popular 1966 animated feature about the Grinch, which remains stylistically true to the original illustrations--for inspiration and ideas.
Local consignment shops are the best target for Whoville-wear. Brightly coloured, outdated dresses and suits that exaggerate form and draw attention to themselves are a fitting choice. For a more abstracted outfit, nightgowns and flannel pyjamas, cloaks, stocking caps, hats with floral arrangements, tights, knee-high stockings and old terry cloth zip-up robes are appropriate.
Look for furry cuffs and trousers that balloon out and then wrap tightly around the ankles. Otherwise, you can use elastic to achieve the same effect. Items that have giant ribbons and bows, polka dots, plaid, stripes and loud patterns are all fitting. For an eclectic look, clothes of clashing colours or strange pattern combinations may be layered.
Whoville hairstyles are variable, but they're mostly bizarre. A woman may choose to wear her hair in a ponytail on top of the head, poofed or curled to sit on top of the head without drooping down. The hair of a woman may also be worn in braids that stick out; use wires for the "Pippi Longstocking" effect. Multiple braids and ponytails may be used on one head.
A man may use styling gel to slick back, curl or stand his hair up in curled, messy spikes. In some cases, antennas may be attached to the head.
Little or no make-up is necessary. However, to add to the overall mania, cheeks may be made rosy; noses may be rosy as well. Women may wear colourful eyeshadow or lipstick. Citizens of Whoville do not actually look very human--presumably because they are not. Yet, without a mask, it would be impossible to mimic the face of a citizen of Whoville.
