If you’re accompanying a Mary Poppins on a date to your next Halloween party, then perhaps you can dress up as Bert. He’s most recognizable in his chimney sweep costume though his Dapper Dan penguin suit is a pretty close second. This costume can be easily pulled off with pieces you may already have in your closet. Start with a dark dress shirt and cover it with a vest. To really pull off the time period be sure to get a beret cap and big red bowtie as shown in the reference photo. Throw in the overalls to compete the look. Also be sure to wear fitted jeans that don’t ride too low for that modern fitted look. If you can pull off this costume, you may steal the show away from Mary Poppins herself!
