Honeydukes is one of the most recognizable stores from the series. Kat, who goes by @kathleezzzy on Instagram, created the perfect outfit to look like a clerk of the candy store in the '40s.
She wore a pink-and-white striped dress, short gloves, white sneakers with ankle socks, and feathers in her hair. She also carried a purse with the Honeydukes logo on it.
You can also take inspiration from other magical businesses like the Leaky Cauldron, Weasleys' Wizard Wheezes, Gringotts Wizarding Bank, and Ollivanders.
