Aloysius O'Hare Costume
Dress up as Thneedville's tiny, greedy air baron this Halloween.
Aloysius O'Hare is the pint-sized, bowl-cut-wearing villain from Illumination's animated adaptation of The Lorax. He is a popular choice for funny, meme-worthy costumes due to his distinctively short stature, oversized collar, and dramatic hair. The look is defined by a bright green suit, a massive white collar, and a perfectly round black bowl cut.

How to put it together
- 1
Put on the white button-up shirt and fasten the slim black necktie.
- 2
Attach the oversized, stiff white collar over your shirt collar so it stands up high and wide.
- 3
Put on the green dress pants and tuck in the white shirt.
- 4
Put on the bright green suit jacket over the shirt and tie, ensuring the large white collar rests outside the jacket lapels.
- 5
Carefully put on the black bowl cut wig, brushing it flat so the bangs are perfectly straight across your forehead.
- 6
Carry your DIY O'Hare Air bottle prop to complete the look.
Makeup & hair
Keep your face clean-shaven or use concealer to hide any facial hair. The hair is the main feature: ensure the black bowl cut wig is perfectly centered, flat, and free of frizz.
